x^2+8xy+y^2 
I just need the answer but really quick

lukecrayonz · Answer

What do you need..

anonymous · Answer

do you want us to solve for x or y?...

lukecrayonz · Answer

Perhaps factor.

insa · Answer

Using perfect square identity u just need to factorize it

insa · Answer

Quick plz

anonymous · Answer

you aren't just meant to give answers on here. Sorry to be a party pooper but that's not the point of the site.

anonymous · Answer

true. no matter how stupid it sounds it will just lead to you falling behind in class. get some help from your teacher! :) @sarahusher @insa

anonymous · Answer

okay why don't you show us your answer and we can help find where you went wrong? (I know the feeling not being able to use youtube!)

insa · Answer

i have (x+y)^2 is it correct?? btw i use youtube by proxy :) but the links actually dont work

jdoe0001 · Answer

hmmm

anonymous · Answer

not quite because: $$(x+y)^{2}=x ^{2}+y ^{2}+2xy$$

insa · Answer

btw thx @jdoe0001

$\bf x^2+8xy+\square^2$     <--- neverminding the "y squared" for now, what value do you think we need there to get a "perfect square trinomial"

insa · Answer

@sarahusher but when we rearrange that would  be fine right?? so no problem??

insa · Answer

@jdoe0001 y^2??

jdoe0001 · Answer

well... ahemm.... well.... not quite....

do you know what the middle term is supposed to be?

jdoe0001 · Answer

the middle term in a perfect square trinomial that is

insa · Answer

when we apply perfect square identity wont it be 2(4)(xy) as when multiplied it would make 8xy?

jdoe0001 · Answer

yeap... so that will uncover stark naked the next term

anonymous · Answer

Sorry I had to do something...looks like @jdoe0001  has got this!

insa · Answer

anyways @jdoe0001 i gtg well that video was helpful bye:)

jdoe0001 · Answer

$\large \begin{array}{llll}
x^2+&8xy+&\square^2\
\downarrow&&\downarrow\
x&2x\square &\square\

\end{array}$

jdoe0001 · Answer

so we can say that $\bf 8xy = 2x\square \implies \cfrac{8xy}{2x}=\square $
