\int_{0}^{5} x^{2} + 2 x - 3 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_{0}^{5} x^{2} d x + \int_{0}^{5} 2 x d x - \int_{0}^{5} 3 d x

\int_{0}^{5} x^{2} d x = \frac{125}{3}

\int_{0}^{5} 2 x d x = 25

\int_{0}^{5} 3 d x = 15

= \frac{125}{3} + 25 - 15

Vereinfache

\frac{125}{3} + 25 - 15 : \frac{155}{3}

= \frac{155}{3}
