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