Learn how to solve integrals with radicals problems step by step online. Find the integral int((x^5-x^2)/(x^3-2x))dx. Divide x^5-x^2 by x^3-2x. Resulting polynomial. Expand the integral \int\left(x^{2}+2+\frac{-x^{2}+4x}{x^3-2x}\right)dx into 3 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}.

Final Answer

$\frac{x^{3}}{3}+2x+\ln\left(\frac{\sqrt{2}}{\sqrt{x^2+2}}\right)+2\sqrt{2}\arctan\left(0.707106x\right)+C_0$
