x^{2} (a^{2} - x^{2})^{2} : a^{4} x^{2} - 2 a^{2} x^{4} + x^{6}

= \int a^{4} x^{2} - 2 a^{2} x^{4} + x^{6} d x

Wende die Summenregel an:

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

= \int a^{4} x^{2} d x - \int 2 a^{2} x^{4} d x + \int x^{6} d x

\int a^{4} x^{2} d x = \frac{a ^{4} x ^{3}}{3}

\int 2 a^{2} x^{4} d x = \frac{2 a ^{2} x ^{5}}{5}

\int x^{6} d x = \frac{x ^{7}}{7}

= \frac{a ^{4} x ^{3}}{3} - \frac{2 a ^{2} x ^{5}}{5} + \frac{x ^{7}}{7}
