Learn how to solve integrals of rational functions problems step by step online. Find the integral int((x^2)/(x+5))dx. Divide x^2 by x+5. Resulting polynomial. Expand the integral \int\left(x-5+\frac{25}{x+5}\right)dx into 3 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int xdx results in: \frac{1}{2}x^2.
