$\int\left(9x^3+7x^2+8\right)^2dx$
Learn how to solve problems step by step online. Find the integral of y=(9x^3+7x^2+8)^2. Find the integral. Rewrite the integrand \left(9x^3+7x^2+8\right)^2 in expanded form. Expand the integral \int\left(81x^{6}+126x^{5}+144x^3+49x^{4}+112x^2+64\right)dx into 6 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int81x^{6}dx results in: \frac{81}{7}x^{7}.
