Learn how to solve problems step by step online. Find the integral int((x^4+2x+1)/(x^3-x^2-2x))dx. Rewrite the expression \frac{x^4+2x+1}{x^3-x^2-2x} inside the integral in factored form. We can factor the polynomial x^4+2x+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^4+2x+1 will then be.
