Learn how to solve integrals of rational functions problems step by step online. Find the integral int((x^2+2x+-1)/(x-4))dx. Divide x^2+2x-1 by x-4. Resulting polynomial. Expand the integral \int\left(x+6+\frac{23}{x-4}\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.
