$\int\left(x^2+x-2\right)dx$
Learn how to solve integral calculus problems step by step online. Factor the expression x^2+x+-2. Find the integral. Expand the integral \int\left(x^2+x-2\right)dx into 3 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int x^2dx results in: \frac{x^{3}}{3}. The integral \int xdx results in: \frac{1}{2}x^2.
