Schritte zur Lösung

\int_{1}^{9} x^{2} + 2 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}^{9} x^{2} d x + \int_{1}^{9} 2 d x

\int_{1}^{9} x^{2} d x = \frac{728}{3}

\int_{1}^{9} 2 d x = 16

= \frac{728}{3} + 16

Vereinfache

\frac{728}{3} + 16 : \frac{776}{3}

= \frac{776}{3}
