x (x - 1)^{3} : x^{4} - 3 x^{3} + 3 x^{2} - x

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

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

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

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

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

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