Problem Statement

Call a polynomial positive reducible if it can be written as a product of two nonconstant polynomials with positive real coefficients. Let f(x) f(x) be a polynomial with f(0)\not\equal{}0 such that f(xn) f(x^n) is positive reducible for some natural number n n. Prove that f(x) f(x) itself is positive reducible. [L. Redei]
