$\int\left(7-2x\right)\left(7+2x\right)dx$
Learn how to solve integral calculus problems step by step online. Find the integral of (7-2x)(7+2x). Find the integral. Rewrite the integrand \left(7-2x\right)\left(7+2x\right) in expanded form. Expand the integral \int\left(49-4x^2\right)dx into 2 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int49dx results in: 49x.
