# Math Help - What does this factorize into?

1. ## What does this factorize into?

y cubed minus x cubed.

Many thanks!

2. Recall that difference of cubes can be factored like the following:

$a^3 - b^3 = (a-b)(a^2+ab+b^2)$

The sum of cubes is also factored in a similar way:

$a^3 + b^3 = (a+b)(a^2-ab+b^2)$
