Simple polynomial

[takercena]

1. Factorize (a-b)^3 + (a+b)^3

2. Attempt of solution are involving cyclic or/and homogeneous polynomials

I want to understand this clearly, can anyone explain this? The answer is 2a(a^2+3b^2)

Try expanding (a+b)^3 and (a-b)^3 and the simplifying, then factorizing.
