Learn how to solve integrals of rational functions problems step by step online. Find the integral int((x^4+x^2+1)/(x-1))dx. Divide x^4+x^2+1 by x-1. Resulting polynomial. Expand the integral \int\left(x^{3}+x^{2}+2x+2+\frac{3}{x-1}\right)dx into 5 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int x^{3}dx results in: \frac{x^{4}}{4}.
