(- 5 x^{2} - 4 x)^{3} : - 125 x^{6} - 300 x^{5} - 240 x^{4} - 64 x^{3}

= \int_{- 2}^{2} - 125 x^{6} - 300 x^{5} - 240 x^{4} - 64 x^{3} 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_{- 2}^{2} 125 x^{6} d x - \int_{- 2}^{2} 300 x^{5} d x - \int_{- 2}^{2} 240 x^{4} d x - \int_{- 2}^{2} 64 x^{3} d x

\int_{- 2}^{2} 125 x^{6} d x = \frac{32000}{7}

\int_{- 2}^{2} 300 x^{5} d x = 0

\int_{- 2}^{2} 240 x^{4} d x = 3072

\int_{- 2}^{2} 64 x^{3} d x = 0

= - \frac{32000}{7} - 0 - 3072 - 0

Vereinfache

- \frac{32000}{7} - 0 - 3072 - 0 : - \frac{53504}{7}

= - \frac{53504}{7}
