$\int\left(y+7\right)\left(y-4\right)dy$
Learn how to solve problems step by step online. Find the integral of (y+7)(y-4). Find the integral. Rewrite the integrand \left(y+7\right)\left(y-4\right) in expanded form. Expand the integral \int\left(y^2+3y-28\right)dy into 3 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int y^2dy results in: \frac{y^{3}}{3}.
