$\int\left(25x^2-36\right)dx$
Learn how to solve integral calculus problems step by step online. Find the integral int((5x+6)(5x-6))dx. Rewrite the integrand \left(5x+6\right)\left(5x-6\right) in expanded form. Expand the integral \int\left(25x^2-36\right)dx into 2 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int25x^2dx results in: \frac{25}{3}x^{3}. The integral \int-36dx results in: -36x.
