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