$\int\left(2x^2+4x\right)dx$
Learn how to solve integral calculus problems step by step online. Find the integral int(x(2x+4))dx. Rewrite the integrand x\left(2x+4\right) in expanded form. Expand the integral \int\left(2x^2+4x\right)dx into 2 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int2x^2dx results in: \frac{2}{3}x^{3}. The integral \int4xdx results in: 2x^2.
