Homework Help: Simple polynomial

  1. May 23, 2008 #1
    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.
