Learn how to solve integrals of rational functions problems step by step online. Find the integral int((2x^3-4x^2-15x+5)/(x^2-2x+-8))dx. Divide 2x^3-4x^2-15x+5 by x^2-2x-8. Resulting polynomial. Expand the integral \int\left(2x+\frac{x+5}{x^2-2x-8}\right)dx into 2 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int2xdx results in: x^2.
