(x^{8} - 4 x^{2})^{3} (x^{7} - x) : x^{31} - 13 x^{25} + 60 x^{19} - 112 x^{13} + 64 x^{7}

= \int x^{31} - 13 x^{25} + 60 x^{19} - 112 x^{13} + 64 x^{7} 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 x^{31} d x - \int 13 x^{25} d x + \int 60 x^{19} d x - \int 112 x^{13} d x + \int 64 x^{7} d x

\int x^{31} d x = \frac{x ^{32}}{32}

\int 13 x^{25} d x = \frac{x ^{26}}{2}

\int 60 x^{19} d x = 3 x^{20}

\int 112 x^{13} d x = 8 x^{14}

\int 64 x^{7} d x = 8 x^{8}

= \frac{x ^{32}}{32} - \frac{x ^{26}}{2} + 3 x^{20} - 8 x^{14} + 8 x^{8}
