Learn how to solve problems step by step online. Find the integral int((7+6x^25x^3)^2)dx. Rewrite the integrand \left(7+6x^2+5x^3\right)^2 in expanded form. Expand the integral \int\left(49+84x^2+70x^3+36x^{4}+60x^{5}+25x^{6}\right)dx into 6 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int49dx results in: 49x. The integral \int84x^2dx results in: 28x^{3}.
