I need help with factoring! x^6-y^6?

OpenStudy (dumbcow):

difference of squares --> (x^3 +y^3)(x^3 -y^3) then 2nd factor is a difference of cubes -->(x^3 +y^3)(x-y)(x^2+xy+y^2)

OpenStudy (anonymous):

(x^3)^2 - (y^3)2

OpenStudy (anonymous):

Hey, you can factorise x^3 + y^3.

OpenStudy (anonymous):

x^3 + y^3 = (x - y)(x^2 + xy + y^2)

OpenStudy (anonymous):

Thank you so much!

yw

OpenStudy (dumbcow):

oh yeah i missed that :) so final answer --> (x-y)(x+y)(x^2+xy+y^2)(x^2-xy+y^2)
