Schritte zur Lösung

\int_{4}^{6} x^{2} + 2 x - 11 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} 11 d x

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

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

\int_{4}^{6} 11 d x = 22

= \frac{152}{3} + 20 - 22

Vereinfache

\frac{152}{3} + 20 - 22 : \frac{146}{3}

= \frac{146}{3}
