Schritte zur Lösung

\int_{- 4}^{4} x^{2} + x - 6 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_{- 4}^{4} x^{2} d x + \int_{- 4}^{4} x d x - \int_{- 4}^{4} 6 d x

\int_{- 4}^{4} x^{2} d x = \frac{128}{3}

\int_{- 4}^{4} x d x = 0

\int_{- 4}^{4} 6 d x = 48

= \frac{128}{3} + 0 - 48

Vereinfache

\frac{128}{3} + 0 - 48 : - \frac{16}{3}

= - \frac{16}{3}
