$\int\left(4x^2-x^{3}\right)dx$
Learn how to solve integral calculus problems step by step online. Find the integral int((4x-x^2)x)dx. Rewrite the integrand \left(4x-x^2\right)x in expanded form. Expand the integral \int\left(4x^2-x^{3}\right)dx into 2 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int4x^2dx results in: \frac{4}{3}x^{3}. The integral \int-x^{3}dx results in: \frac{-x^{4}}{4}.
