Learn how to solve integrals of rational functions problems step by step online. Find the integral int((x^4+x+1)/(x^2+8x+-2))dx. Divide x^4+x+1 by x^2+8x-2. Resulting polynomial. Expand the integral \int\left(x^{2}-8x+66+\frac{-543x+133}{x^2+8x-2}\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}.
