Learn how to solve integrals by partial fraction expansion problems step by step online. Integral of (2x^2+3)/(x^3-2x^2+x) with respect to x. We can factor the polynomial x^3-2x^2+x 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 0. Next, list all divisors of the leading coefficient a_n, which equals 1. The possible roots \pm\frac{p}{q} of the polynomial x^3-2x^2+x will then be. We can factor the polynomial x^3-2x^2+x using synthetic division (Ruffini's rule). We found that 1 is a root of the polynomial.
