$\int\left(3a^2+2b\right)\left(3a^2-2b\right)db$
Learn how to solve integral calculus problems step by step online. Find the integral of (3a^2+2b)(3a^2-2b). Find the integral. Rewrite the integrand \left(3a^2+2b\right)\left(3a^2-2b\right) in expanded form. Expand the integral \int\left(9a^{4}-4b^2\right)db into 2 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int9a^{4}db results in: \frac{9}{5}a^{5}.
