Lösung

\frac{9}{2}

+1

Dezimale

4.5

Schritte zur Lösung

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

\int_{- 2}^{1} 2 d x = 6

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

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

= 6 - 3 - (- \frac{3}{2})

Vereinfache

6 - 3 - (- \frac{3}{2}) : \frac{9}{2}

= \frac{9}{2}
