\int_{- 1}^{0} x (x + 1)^{100} d x

Wende U-Substitution an

= \int_{0}^{1} (u - 1) u^{100} d u

(u - 1) u^{100} : u^{101} - u^{100}

= \int_{0}^{1} u^{101} - u^{100} d u

Wende die Summenregel an:

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

= \int_{0}^{1} u^{101} d u - \int_{0}^{1} u^{100} d u

\int_{0}^{1} u^{101} d u = \frac{1}{102}

\int_{0}^{1} u^{100} d u = \frac{1}{101}

= \frac{1}{102} - \frac{1}{101}

Vereinfache

\frac{1}{102} - \frac{1}{101} : - \frac{1}{10302}

= - \frac{1}{10302}
