Schritte zur Lösung

\int_{3}^{8} x^{2} - 9 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_{3}^{8} x^{2} d x - \int_{3}^{8} 9 d x

\int_{3}^{8} x^{2} d x = \frac{485}{3}

\int_{3}^{8} 9 d x = 45

= \frac{485}{3} - 45

Vereinfache

\frac{485}{3} - 45 : \frac{350}{3}

= \frac{350}{3}
