(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

My book says that one "easily" verifies that

(x+y)^n = (x + y)^(n-2)Q+(x+y)^(n-3)P where

Q = x^2 + xy +y^2

and

P = xy^2 + x^2y

2. Relevant equations

3. The attempt at a solution

I began by expanding everything into summations with binomial coefficients and it seemed like that method would work but it seemed rather far from easy.
