Schritte zur Lösung

\int_{0}^{4} x^{2} - 8 x 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}^{4} x^{2} d x - \int_{0}^{4} 8 x d x

\int_{0}^{4} x^{2} d x = \frac{64}{3}

\int_{0}^{4} 8 x d x = 64

= \frac{64}{3} - 64

Vereinfache

\frac{64}{3} - 64 : - \frac{128}{3}

= - \frac{128}{3}

\int_{1}^{2} \frac{x ^{2} + x ^{4}}{x ^{2}} d x
