Schritte zur Lösung

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

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

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

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

= 3 + 3 - \frac{3}{2}

Vereinfache

3 + 3 - \frac{3}{2} : \frac{9}{2}

= \frac{9}{2}
