Learn how to solve problems step by step online. Integrate the function (x^3-6x+-20)/(x+5) from 1 to 2. Divide x^3-6x-20 by x+5. Resulting polynomial. Expand the integral \int_{1}^{2}\left(x^{2}-5x+19+\frac{-115}{x+5}\right)dx into 4 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int_{1}^{2} x^{2}dx results in: \frac{7}{3}.
