Schritte zur Lösung

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

\int_{- 3}^{1} x^{2} d x = \frac{28}{3}

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

\int_{- 3}^{1} 3 d x = 12

= \frac{28}{3} - 8 - 12

Vereinfache

\frac{28}{3} - 8 - 12 : - \frac{32}{3}

= - \frac{32}{3}
