Schritte zur Lösung

\int_{- \frac{3}{2}}^{1} x^{3} - 3 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_{- \frac{3}{2}}^{1} x^{3} d x - \int_{- \frac{3}{2}}^{1} 3 x d x

\int_{- \frac{3}{2}}^{1} x^{3} d x = - \frac{65}{64}

\int_{- \frac{3}{2}}^{1} 3 x d x = - \frac{15}{8}

= - \frac{65}{64} - (- \frac{15}{8})

Vereinfache

- \frac{65}{64} - (- \frac{15}{8}) : \frac{55}{64}

= \frac{55}{64}
