$\int\left(9x^2-2x-1\right)dx$
Learn how to solve integral calculus problems step by step online. Factor the expression 9x^2-2x+-1. Find the integral. Expand the integral \int\left(9x^2-2x-1\right)dx into 3 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int9x^2dx results in: 3x^{3}. The integral \int-2xdx results in: -x^2.
