Schritte zur Lösung

\int_{4}^{6} x^{2} + 2 x - 5 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}^{6} x^{2} d x + \int_{4}^{6} 2 x d x - \int_{4}^{6} 5 d x

\int_{4}^{6} x^{2} d x = \frac{152}{3}

\int_{4}^{6} 2 x d x = 20

\int_{4}^{6} 5 d x = 10

= \frac{152}{3} + 20 - 10

Vereinfache

\frac{152}{3} + 20 - 10 : \frac{182}{3}

= \frac{182}{3}
