Final answer to the problem
Step-by-step Solution
Learn how to solve integrals of polynomial functions problems step by step online. Integrate int(6x^2-4x+9)dx. Expand the integral \int\left(6x^2-4x+9\right)dx into 3 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int6x^2dx results in: 2x^{3}. The integral \int-4xdx results in: -2x^2. The integral \int9dx results in: 9x.
