Best ResponseYou've already chosen the best response.1oh there two pages last 4 you are reffering to page 2 right?

Best ResponseYou've already chosen the best response.1okay! first pages looks like an example to me

Best ResponseYou've already chosen the best response.0i think i need to answer the 4 questions at the bottom of pg 2

Best ResponseYou've already chosen the best response.1anyways we are doing this \(\sqrt{(x^2x)+7}=2(x^2x)1\) 1) is about the u

Best ResponseYou've already chosen the best response.0there is no u there, but in pg 11 it says let u= t^23t is that right?

Best ResponseYou've already chosen the best response.1it say what would u represent i may reading this incorrectly lol

xapproachesinfinity

Best ResponseYou've already chosen the best response.1they want you to suggest a u for that equation

Best ResponseYou've already chosen the best response.0idk im very confused i dont see a U?? :S

xapproachesinfinity

Best ResponseYou've already chosen the best response.1no there is no u in the problem! what they are telling you is do substitution instead of solving for x we solve for a new variable u but we need first to make some kind of substitution if you looked at the first page you have they give you an example

xapproachesinfinity

Best ResponseYou've already chosen the best response.1i think you didn;t read what that page is saying otherwise you would be confused what u is lol

xapproachesinfinity
 one year ago
Best ResponseYou've already chosen the best response.1because that first page explains it all!

xapproachesinfinity

Best ResponseYou've already chosen the best response.1lol! okay no problem so we need to do substitution to some variable u I'm speaking of this equation now \(\sqrt{(x^2x)+7}=2(x^2x)1\)

xapproachesinfinity
 one year ago
Best ResponseYou've already chosen the best response.1this equation looks a mess for now that's why we do u to have only one good looking variable

anonymous

Best ResponseYou've already chosen the best response.0so we need to replace (x^2x) with u right

xapproachesinfinity

Best ResponseYou've already chosen the best response.1so we can solve easily ah yes you are catching good going so far

xapproachesinfinity

Best ResponseYou've already chosen the best response.1\(\sqrt{u+7}=2u1\) letting u=x^2x yes

xapproachesinfinity
 one year ago
Best ResponseYou've already chosen the best response.1now we can solve for u before we go back to x

xapproachesinfinity

Best ResponseYou've already chosen the best response.1following?

xapproachesinfinity
 one year ago
Best ResponseYou've already chosen the best response.1\(\sqrt{u+7}=2u1 \Longrightarrow u+7=(2u1)^2\)

xapproachesinfinity

Best ResponseYou've already chosen the best response.1agree with this step or no?

xapproachesinfinity

Best ResponseYou've already chosen the best response.1i took square of both sides

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0to get rid of the sqrt, yea

xapproachesinfinity

Best ResponseYou've already chosen the best response.1good! so now \(u+7=4u^24u+1 \Longrightarrow 4u^25u6=0\)

xapproachesinfinity

Best ResponseYou've already chosen the best response.1we got a quadratic!

xapproachesinfinity
 one year ago
Best ResponseYou've already chosen the best response.1can we factor that!

xapproachesinfinity
 one year ago
Best ResponseYou've already chosen the best response.1yes! any questions

anonymous

Best ResponseYou've already chosen the best response.0to get 4u^2 5u6, you just did u7 from both sides right?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0and then we need to factr that to (4u+3)(u2)?

xapproachesinfinity
 one year ago
Best ResponseYou've already chosen the best response.1now we factor to \((u2)(4u+3)=0\)

xapproachesinfinity

Best ResponseYou've already chosen the best response.1yes excellent

xapproachesinfinity

Best ResponseYou've already chosen the best response.1solve for u what is zpp lol never heard this haha

anonymous

Best ResponseYou've already chosen the best response.0zero product property lol

xapproachesinfinity

Best ResponseYou've already chosen the best response.1i guess you mean u2=0 or 4u+3=0 u=2 or u=3/4

xapproachesinfinity

Best ResponseYou've already chosen the best response.1eh i see i never named anyhing it just makes sense to me with no name haha

xapproachesinfinity
 one year ago
Best ResponseYou've already chosen the best response.1now we solved for u but we still not finished for x

xapproachesinfinity
 one year ago
Best ResponseYou've already chosen the best response.1remember that we let u=x^2x right

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0so for the first question its u= *3/4 and u=2 right

xapproachesinfinity
 one year ago
Best ResponseYou've already chosen the best response.1so we have \(x^2x=2 ~~or~~ x^2x=3/4\)

xapproachesinfinity
 one year ago
Best ResponseYou've already chosen the best response.1oh no first question to just answer u=x^2x that is it

xapproachesinfinity
 one year ago
Best ResponseYou've already chosen the best response.1we are actually doing all those 4 question in one go

xapproachesinfinity
 one year ago
Best ResponseYou've already chosen the best response.1once we finish you put it in order 1 put what we did 2 put what we did

xapproachesinfinity

Best ResponseYou've already chosen the best response.1here i went to answer those as one question lol they supposed to be one it is just that they want you to understand it part by part

xapproachesinfinity

Best ResponseYou've already chosen the best response.12 we did we wrote the equATION WITH ONLY U

xapproachesinfinity

Best ResponseYou've already chosen the best response.13 we did we solved for u u=2 u=3/4

xapproachesinfinity

Best ResponseYou've already chosen the best response.1we are in 4 now :)

xapproachesinfinity

Best ResponseYou've already chosen the best response.1\(x^2x=2 ~~or x^2x=3/4 \) we solve this now

xapproachesinfinity

Best ResponseYou've already chosen the best response.1two quadratic equations

xapproachesinfinity

Best ResponseYou've already chosen the best response.1\(x^2x2=0 ~~~or ~~~ 4x^24x+3=0\)

xapproachesinfinity

Best ResponseYou've already chosen the best response.1looks good to you?

xapproachesinfinity

Best ResponseYou've already chosen the best response.1may be i wen too fast haha x^2x=2 x^2x2=0 after subtracting 2 from both ssides

anonymous

Best ResponseYou've already chosen the best response.0how did you get 4x^24x+3

xapproachesinfinity
 one year ago
Best ResponseYou've already chosen the best response.1the other one x^2x=3/4 ===> 4(x^2x)=3 (multiplied 4 both sides) 4x^24x=3 4x^24x+3=0 added 3 to both sides

xapproachesinfinity
 one year ago
Best ResponseYou've already chosen the best response.1clear now i guess haha

xapproachesinfinity

Best ResponseYou've already chosen the best response.0i was just trying to understand it sorry, im a slow learner lol i got it tho

xapproachesinfinity

Best ResponseYou've already chosen the best response.1hmm you are good learner as i see it :)

xapproachesinfinity
 one year ago
Best ResponseYou've already chosen the best response.1we solve \(x^2x2=0 \Longrightarrow (x+1)(x2)=0\)

xapproachesinfinity

Best ResponseYou've already chosen the best response.1this one 4x^24x+3=0 does not have real solutions

xapproachesinfinity
 one year ago
Best ResponseYou've already chosen the best response.1so we just solve (x+1)(x2)=0

xapproachesinfinity

Best ResponseYou've already chosen the best response.1yes great job

xapproachesinfinity

Best ResponseYou've already chosen the best response.1that for step 4 and we are good!
