Schritte zur Lösung

\int_{0}^{4} x (4 x - x^{2}) d x

Multipliziere aus

x (4 x - x^{2}) : 4 x^{2} - x^{3}

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

\int_{0}^{4} 4 x^{2} d x = \frac{256}{3}

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

= \frac{256}{3} - 64

Vereinfache

\frac{256}{3} - 64 : \frac{64}{3}

= \frac{64}{3}
