$\int\left(21x^2+11x-2\right)dx$
Learn how to solve integral calculus problems step by step online. Integrate the function 21x^2+11x+-2. Find the integral. Expand the integral \int\left(21x^2+11x-2\right)dx into 3 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int21x^2dx results in: 7x^{3}. The integral \int11xdx results in: \frac{11}{2}x^2.
