integral from 0 to a of (a^2x-x^3)

\int_{0}^{a} (a^{2} x - x^{3}) d x

\frac{a ^{4}}{2} - \frac{a ^{4}}{4}

Solution steps

\int_{0}^{a} a^{2} x - x^{3} d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int_{0}^{a} a^{2} x d x - \int_{0}^{a} x^{3} d x

\int_{0}^{a} a^{2} x d x = \frac{a ^{4}}{2}

\int_{0}^{a} x^{3} d x = \frac{a ^{4}}{4}

= \frac{a ^{4}}{2} - \frac{a ^{4}}{4}
