Best ResponseYou've already chosen the best response.0You need to distribute through to simplify. What do you not understand?

Best ResponseYou've already chosen the best response.0Ok. Well when you multiply variables the format is as follows. Let * be multiplication. \[x*x=x^2\] and \[x*x*x=x^3\] and so on.

Best ResponseYou've already chosen the best response.0So maybe it's easier to work through the problem, or just spit out the answer like what has been done already.

Best ResponseYou've already chosen the best response.0cyter how did you come up with that . if that is the answer fine but that dose not tell me how to do it

Best ResponseYou've already chosen the best response.0Ok so the first part you have 4y(3y). The parenthesis just separate quantities and mean to multiple. So 4 times 3 give 12 and y times y gives y². Thus you get 12y² for the first part. Does this make sense?

Best ResponseYou've already chosen the best response.0Multiply* not multiple.

Best ResponseYou've already chosen the best response.0sorry thats wrong 4(3y)5+2(5y+7) this is the correct one

anonymous

Best ResponseYou've already chosen the best response.0Ok well you do the same process. So 4(3y) gives 12y. All I did was multiple what is in parenthesis by 4. Then you subtract 5 giving you 12y5+2(5y+7). To simplify the 2(5y+7) you multiply what's in parenthesis by what is right outside the parenthesis. So 2 times (5y+7). So what does 2(5y+7) equal when you multiply it out?

Best ResponseYou've already chosen the best response.0Not quite. 2(5y+7)=10y+14. You multiply each thing in the parenthesis by 2.

Best ResponseYou've already chosen the best response.0So once we have simplified all parts we get: 12y5+10y+14. The last step is to add things that look alike.

Best ResponseYou've already chosen the best response.0You are correct above. But you can't forget the y. The y is a variable and the 5 is a coefficient. When you multiply variables by a number you just get that many variables. So 3 times y gives 3y, 7 times x gives 7x.

Best ResponseYou've already chosen the best response.0Ok so not sure if you were understanding how we got to 12y5+10y+14 but if we do continue when I say add like terms I mean add any regular numbers so like 5 and 14 to get 9 and add any variables that look the same. 12y and 10y look the same. Both have a y and both have coefficients. So 12y+10y=2y I added the 12 and 10 and just kept the y. Final answer should be 2y+9

Best ResponseYou've already chosen the best response.0ok can we try another one

Best ResponseYou've already chosen the best response.0Now remember what I said. The number in front of the parenthesis is multiplied to each term inside the parenthesis and if there is a variable, b for example, do not leave it off.

Best ResponseYou've already chosen the best response.0okdo i start with 4*3 or 2*6b or dose it matter

anonymous

Best ResponseYou've already chosen the best response.0You can start wherever you like. I normally work from the left to the right so I don't forget anything :)

Best ResponseYou've already chosen the best response.0Close. Don't forget the negative sign. So 12b

anonymous

Best ResponseYou've already chosen the best response.0should it look like that

anonymous

Best ResponseYou've already chosen the best response.0or it should be a 2 at the end

anonymous

Best ResponseYou've already chosen the best response.0Should be a 2 at the end and don't forget the 10 at the beginning. So after simplifying a little you get 1012b+12+12b2

Best ResponseYou've already chosen the best response.0now we add the like #first

anonymous

Best ResponseYou've already chosen the best response.0Yes now you add the like terms.

anonymous

Best ResponseYou've already chosen the best response.0You have 12b+12b so you have a negative 12b plus a positive 12b what does that give you? Not 24b.

anonymous

Best ResponseYou've already chosen the best response.0Nope. If you have 12 of something and then take away 12 of something you are left with zero. 12b+12b=0

Best ResponseYou've already chosen the best response.05*2=10 A negative number times a positive number is a negative number. A negative number times a negative number is a positive number.

Best ResponseYou've already chosen the best response.0should it read 14+7+6x+6+16 i hope!!

Best ResponseYou've already chosen the best response.0i for got the perentacies around the 7 because of the two signs together

anonymous

Best ResponseYou've already chosen the best response.0Forgot the +16 on the end. So 5x10x8x6x6+16

Best ResponseYou've already chosen the best response.0so were did i go wrong

anonymous

Best ResponseYou've already chosen the best response.0Mean 1, no. There is a 1 coefficient in front of the x. So x is the same as 1x.

anonymous

Best ResponseYou've already chosen the best response.0so wouldn't that be 8*1x=7

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0No. You are multiplying, not adding. 8*(1x)=8x if you cannot add these terms since they aren't "like" terms.

anonymous

Best ResponseYou've already chosen the best response.0I'm going to go. But I will leave you with the work for the problem and maybe from what we've discussed you can figure it out.

Best ResponseYou've already chosen the best response.05(x+2)+8(x)+3(2x2)+16 5x108x6x6+16 here I just multiplied through 9x+0 here I added like terms (added the numbers with the x's by themselves to get 9x and then the numbers by themselves to get 106+16=0
