HELP ME \[1-3a^2+3a^4-a^6\]

OpenStudy (anonymous):

we have to factorize 1-3a^2+3a^4-a^6

OpenStudy (riley):

ooooh this looks like fun, lemme grab a pencil and some paper

OpenStudy (riley):

factor it completely?

OpenStudy (anonymous):

yes i think it can be solved through (a-b)^3

OpenStudy (anonymous):

i meant this is in the form of a^3-b^3-3ab(a-b) that is (a-b)^3

OpenStudy (riley):

k give me a sec, i have to write all this crap down when i work through it

OpenStudy (riley):

Kush I came up with -(a-1)^3 * (a+1)^3

OpenStudy (riley):

lemme go back and check my work again though

OpenStudy (anonymous):

did u mean \[(1-a)^3(1+a)^3\]

OpenStudy (anonymous):

I got \[-(a^2 - 1)^3\]

OpenStudy (anonymous):

Damn, which is equivalent to what you got

OpenStudy (riley):

yeah, thats the answer my bf came up with. But I told him I was still correct b/c it's the same as my answer haha.

OpenStudy (anonymous):

the answer it is showing is \[(1-a)^3(1+a)^3\]

OpenStudy (anonymous):

What do you mean by "IT"?

OpenStudy (riley):

where did your negative sign go?

OpenStudy (anonymous):

Hehehe women are always right ;)

OpenStudy (anonymous):

can u say the solution any1

OpenStudy (riley):

lol not really >_<

OpenStudy (anonymous):

Well, the solution is already there, in two different, albeit correct, forms

OpenStudy (anonymous):

but the answers are different

OpenStudy (anonymous):

And yet they are both equivalent

OpenStudy (riley):

lol yes, he's very right. there both equivalent, so you got twice what you were looking for! =3
