Schritte zur Lösung

\int_{3}^{5} x^{2} + 2 x - 6 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}^{5} x^{2} d x + \int_{3}^{5} 2 x d x - \int_{3}^{5} 6 d x

\int_{3}^{5} x^{2} d x = \frac{98}{3}

\int_{3}^{5} 2 x d x = 16

\int_{3}^{5} 6 d x = 12

= \frac{98}{3} + 16 - 12

Vereinfache

\frac{98}{3} + 16 - 12 : \frac{110}{3}

= \frac{110}{3}
