(5 + x^{3}) (4 - x^{2}) : 20 - 5 x^{2} + 4 x^{3} - x^{5}

= \int 20 - 5 x^{2} + 4 x^{3} - x^{5} 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 20 d x - \int 5 x^{2} d x + \int 4 x^{3} d x - \int x^{5} d x

\int 20 d x = 20 x

\int 5 x^{2} d x = \frac{5 x ^{3}}{3}

\int 4 x^{3} d x = x^{4}

\int x^{5} d x = \frac{x ^{6}}{6}

= 20 x - \frac{5 x ^{3}}{3} + x^{4} - \frac{x ^{6}}{6}
