$\int\left(x^2-16\right)dx$
Learn how to solve integral calculus problems step by step online. Find the integral int((x-4)(x+4))dx. Rewrite the integrand \left(x-4\right)\left(x+4\right) in expanded form. Expand the integral \int\left(x^2-16\right)dx into 2 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-16dx results in: -16x.
