$\int\left(\frac{2a}{5}+4\right)\left(\frac{2a}{5}-3\right)da$
Learn how to solve integral calculus problems step by step online. Find the integral of ((2a)/5+4)((2a)/5-3). Find the integral. Rewrite the integrand \left(\frac{2a}{5}+4\right)\left(\frac{2a}{5}-3\right) in expanded form. Expand the integral \int\left(\frac{4a^2}{25}+\frac{2a}{5}-12\right)da into 3 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int\frac{4a^2}{25}da results in: \frac{4}{75}a^{3}.
