Best ResponseYou've already chosen the best response.0in this problem the first clue is being = 0 usally says Quad needs to be used.

Best ResponseYou've already chosen the best response.1What is the easier way of working out qUADRATIC without using the quad formula?

Best ResponseYou've already chosen the best response.064^2 is a peferct square so that always tells that this will invole in a square root to slove

godorovg

Best ResponseYou've already chosen the best response.0you could use a^2+B^2=c^2 as well

Best ResponseYou've already chosen the best response.1So I got 1.125, 1.125. Can I write 1.125^2. Or is this considered incorrect?

godorovg
 2 years ago
Best ResponseYou've already chosen the best response.0yes you can do that with 1.125^2 if you used the Quad form you would plus ninus which is what the problem is asking for..

Best ResponseYou've already chosen the best response.1Ok i just wrote it twice. lets see if it counts it correct?

godorovg

Best ResponseYou've already chosen the best response.0treydwg first thing to know in this problem 64s^2+144s+81=0 all of the numbers are perfect squares. what that means taking the square root will be a number for example you take square root of 81 which is, we can check this by 9^2 and yes it equals 9.

Best ResponseYou've already chosen the best response.1what about 2v^2+7v+5 and I need tofactor by grouping?

treydwg

Best ResponseYou've already chosen the best response.1I am at (2v^2+5v)(2v+5) and stuck

treydwg

Best ResponseYou've already chosen the best response.1@godorovg can you assist?

treydwg

Best ResponseYou've already chosen the best response.1where do I go from here?

godorovg

Best ResponseYou've already chosen the best response.0in this problem we need to use F,.O.I .L

godorovg
 2 years ago
Best ResponseYou've already chosen the best response.0so now take the 2v^2 and times to 2v what is the answer

godorovg
 2 years ago
Best ResponseYou've already chosen the best response.04v is right your power is wrong

treydwg
 2 years ago
Best ResponseYou've already chosen the best response.1where are you getting the 2v^2*2v?

godorovg
 2 years ago
Best ResponseYou've already chosen the best response.0because you typed 4v^2 while ago

godorovg
 2 years ago
Best ResponseYou've already chosen the best response.0recall the problem here (2v^2+5v)(2v+5)

treydwg
 2 years ago
Best ResponseYou've already chosen the best response.1the (2v+5) is where im stuck

treydwg

Best ResponseYou've already chosen the best response.1what can I factor out of that?

godorovg
 2 years ago
Best ResponseYou've already chosen the best response.0now 4v is right because 2v times 2v =4v^2 but that is not what is happening here. You have a power being times by V what is the power of the V? that power of the V is ^1 and when times 2v^2 time 2v = 4v^3

godorovg
 2 years ago
Best ResponseYou've already chosen the best response.0so what happened here is we times the 2's to get 4 and v^2 + v^1 =V^3 see that

treydwg

Best ResponseYou've already chosen the best response.1let me look at that hold on

treydwg

Best ResponseYou've already chosen the best response.1now how do I fix the last part?

godorovg
 2 years ago
Best ResponseYou've already chosen the best response.0if you have a question plz ask me..

godorovg
 2 years ago
Best ResponseYou've already chosen the best response.0factoring will not be in use unti we finish F.O.I.L

treydwg
 2 years ago
Best ResponseYou've already chosen the best response.1I have (2v+5) how can I faactor this

godorovg
 2 years ago
Best ResponseYou've already chosen the best response.0no you can not factor that..

treydwg
 2 years ago
Best ResponseYou've already chosen the best response.1ok I see now so this is what I have after foil 4v^3+10v^2+35v

godorovg
 2 years ago
Best ResponseYou've already chosen the best response.0no grouping there are no a like terms here

treydwg
 2 years ago
Best ResponseYou've already chosen the best response.1I know but i was going to use 35v and try to make another number to group

godorovg
 2 years ago
Best ResponseYou've already chosen the best response.0okay let us look at this 4v^3+10v^2+35v what is the same with all the numbers?

godorovg
 2 years ago
Best ResponseYou've already chosen the best response.0yes V so how many V's can be factored?

godorovg
 2 years ago
Best ResponseYou've already chosen the best response.0now look at the numbers what can each number be divided by?

godorovg
 2 years ago
Best ResponseYou've already chosen the best response.0that is the answer it can not be factored any further

treydwg
 2 years ago
Best ResponseYou've already chosen the best response.1ahhhhhhh! Thats my problem i want to always factor further :/

godorovg
 2 years ago
Best ResponseYou've already chosen the best response.0treydwg here is a help for you, if you have done all the factoring right than find a number that divides in to the first and see if it works for example 2 will go ino 4 =2 2 will also go into 10 five times but here is a question for you will 2 divide even into 35?

godorovg
 2 years ago
Best ResponseYou've already chosen the best response.0if the answer is no than you are finished..

treydwg

Best ResponseYou've already chosen the best response.1no it wont and that was my problem

godorovg

Best ResponseYou've already chosen the best response.05x3=14x+6 get a like terms together so we x terms let us put the tgether like this 14x5x=63 recall when a + or  crosses the equals sign it changes

treydwg

Best ResponseYou've already chosen the best response.1ok i did that one a little wrong thank you

treydwg

Best ResponseYou've already chosen the best response.1now this one is throwing me off cuz the a^2 I have a^2=103a I got a^2=5/2

godorovg
 2 years ago
Best ResponseYou've already chosen the best response.0no now think about this one? come you do it!!

godorovg
 2 years ago
Best ResponseYou've already chosen the best response.0first off you can not a^2 = 10 3a and come out with a^2=5/2 no..

godorovg
 2 years ago
Best ResponseYou've already chosen the best response.0hint what happens to the problem when all nunbers are moved like this a^2+3a10= what is this problem?

godorovg
 2 years ago
Best ResponseYou've already chosen the best response.0what did I say when a problem is set to zero is?

treydwg
 2 years ago
Best ResponseYou've already chosen the best response.1or they are all on one side rather

godorovg
 2 years ago
Best ResponseYou've already chosen the best response.0recall the problem a^2 = 10 3a now look at the problem a^2+3a10=

treydwg
 2 years ago
Best ResponseYou've already chosen the best response.1we have to find something in common

godorovg
 2 years ago
Best ResponseYou've already chosen the best response.0so what type of problem is this? not factoring

treydwg
 2 years ago
Best ResponseYou've already chosen the best response.1so i need to find out what two numbers product is 10 and sum is 3 right?

godorovg
 2 years ago
Best ResponseYou've already chosen the best response.0yes but I will let you try this way.

treydwg
 2 years ago
Best ResponseYou've already chosen the best response.1awesome thank you again!

treydwg
 2 years ago
Best ResponseYou've already chosen the best response.1so the solution set is (a+5)(a2)?

godorovg
 2 years ago
Best ResponseYou've already chosen the best response.0now I want you to check this

godorovg
 2 years ago
Best ResponseYou've already chosen the best response.0simply take this (a+5)(a2) use F.O.I.L and see if you get this back a^2+3a10=

godorovg
 2 years ago
Best ResponseYou've already chosen the best response.0if you do than you are right..

godorovg

Best ResponseYou've already chosen the best response.0treydwg if you need help let me know..

treydwg

Best ResponseYou've already chosen the best response.1now I got this one wrong? dont know why? r^2+2r48 I got (r+8)(r6)

treydwg

Best ResponseYou've already chosen the best response.1sorry working on another one

godorovg

Best ResponseYou've already chosen the best response.0which the  to 8 and try again

treydwg
 2 years ago
Best ResponseYou've already chosen the best response.1that gives me a +48 and not 48

treydwg

Best ResponseYou've already chosen the best response.1i am pretty sure im right but the computer counted it wrong??

godorovg
 2 years ago
Best ResponseYou've already chosen the best response.0treydwg is this a test?

treydwg
 2 years ago
Best ResponseYou've already chosen the best response.1yeah but I have three times to take

treydwg
 2 years ago
Best ResponseYou've already chosen the best response.1I can not figure this out and i know im right!

treydwg
 2 years ago
Best ResponseYou've already chosen the best response.1can you figure out why its wrong?

treydwg
 2 years ago
Best ResponseYou've already chosen the best response.1I have already taken the test. just reviewing results

godorovg
 2 years ago
Best ResponseYou've already chosen the best response.0okay that is better, I can get big trouble for helping on tests..

godorovg
 2 years ago
Best ResponseYou've already chosen the best response.0because you have taken it already no worries

treydwg
 2 years ago
Best ResponseYou've already chosen the best response.1yes all done and really confused because my answers I beleive are correct. There are many more like that. Have you figured out why im wrong?

godorovg
 2 years ago
Best ResponseYou've already chosen the best response.0okay try 24 times and see what happens and work it again
