Question

please help!
What is the complete factorization of (x^6 - 64)

Answer 1

I would start with the lower powers first
(x^3)^2 - 8^2 = , which is a difference of squares.
(x^3 - 8)( x^3 + 8). now you can factor a sum of cubes and a difference of cubes

Answer 2

thank you!! @perl
so on my hw one of the choices is (x^3 - 8)( x^3 + 8)
is that the correct answer? :o
