Schritte zur Lösung

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

\int_{- 2}^{3} x^{2} d x = \frac{35}{3}

\int_{- 2}^{3} 2 x d x = 5

\int_{- 2}^{3} 1 d x = 5

= \frac{35}{3} - 5 + 5
