$\int\left(a+3\right)\left(a-1\right)da$
Learn how to solve integral calculus problems step by step online. Find the integral of (a+3)(a-1). Find the integral. Rewrite the integrand \left(a+3\right)\left(a-1\right) in expanded form. Expand the integral \int\left(a^2+2a-3\right)da into 3 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int a^2da results in: \frac{a^{3}}{3}.
