$\int\left(9x^2-4\right)dx$
Learn how to solve integral calculus problems step by step online. Find the integral int((3x+2)(3x-2))dx. Rewrite the integrand \left(3x+2\right)\left(3x-2\right) in expanded form. Expand the integral \int\left(9x^2-4\right)dx into 2 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int9x^2dx results in: 3x^{3}. The integral \int-4dx results in: -4x.
