$\int\left(x+8\right)\left(x+2\right)dx$
Learn how to solve integral calculus problems step by step online. Integrate the function (x+8)(x+2). Find the integral. Rewrite the integrand \left(x+8\right)\left(x+2\right) in expanded form. Expand the integral \int\left(x^2+10x+16\right)dx into 3 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int x^2dx results in: \frac{x^{3}}{3}.
