Learn how to solve integrals of rational functions problems step by step online. Find the integral int((x^3)/(x+1))dx. Divide x^3 by x+1. Resulting polynomial. Expand the integral \int\left(x^{2}-x+1+\frac{-1}{x+1}\right)dx into 4 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int x^{2}dx results in: \frac{x^{3}}{3}.
