Learn how to solve factor by difference of squares problems step by step online. Simplify the expression f(x)=4/(1-x^6). For easier handling, reorder the terms of the polynomial -x^6+1 from highest to lowest degree. We can factor the polynomial -x^6+1 using the rational root theorem, which guarantees that for a polynomial of the form a_nx^n+a_{n-1}x^{n-1}+\dots+a_0 there is a rational root of the form \pm\frac{p}{q}, where p belongs to the divisors of the constant term a_0, and q belongs to the divisors of the leading coefficient a_n. List all divisors p of the constant term a_0, which equals 1. Next, list all divisors of the leading coefficient a_n, which equals 1. The possible roots \pm\frac{p}{q} of the polynomial -x^6+1 will then be.

Final answer to the problem

$f\left(x\right)=\frac{4}{-\left(x^{4}+x^2+1\right)\left(x^2-1\right)}$
