$\int a^2\left(x+1\right)\left(x-1\right)dx$
Learn how to solve integral calculus problems step by step online. Integrate the function a^2(x+1)(x-1). Find the integral. The integral of a function times a constant (a^2) is equal to the constant times the integral of the function. Rewrite the integrand \left(x+1\right)\left(x-1\right) in expanded form. Expand the integral \int\left(x^2-1\right)dx into 2 integrals using the sum rule for integrals, to then solve each integral separately.
