I'm thinking its (x^3-8)(x^3+8) from a difference of cubes, but from a difference of squares it can be (x^2-4)(x^4+4x^2+16).

But then neither of those are prime...

can anyone help me out?

heres what you do

the first thing you had right with the difference of squares actually
take it to (x^3-8)*(x^3+8)

after that, there are formulas for sum and difference of cubes, i think. use them to factor the remaining equations. you can do it separately then throw it all back together if it makes it that much easier

btw, 2^3=8

hope that helped

yeah, thats me

i got (x+2)(x-2)(x+2)(x-2)(x+2)(x-2)

would that be the prime polynomials?

Also, I just heard a program I have on my laptop, Maple 11, which can solve x^6-64 for me, and gave me (x-2)(x+2)(x^2 + 2x + 4)(x^2 - 2x + 4)

would mine still be right though? I just don't know how Maple 11 got that one, doesn't show the work xO lol
