Factor 1) x^4-16y^4

Difference of two squares. $(x^{2})^{2}-(4y^{2})^{2}$

I assume you already know that the difference of two squares factorization is

$x^{2}-y^{2}=(x+y)(x-y)$

Quote:

2)y^6-8x^3

Difference of two cubes:

$x^{3}-y^{3}=(x-y)(x^{2}+xy+y^{2})$

$(y^{2})^{3}-(2x)^{3}$

alrite thanks 4 your help! =)
