x^{3} (1 + x)^{2} : x^{3} + 2 x^{4} + x^{5}

= \int_{0}^{1} x^{3} + 2 x^{4} + x^{5} 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}^{1} x^{3} d x + \int_{0}^{1} 2 x^{4} d x + \int_{0}^{1} x^{5} d x

\int_{0}^{1} x^{3} d x = \frac{1}{4}

\int_{0}^{1} 2 x^{4} d x = \frac{2}{5}

\int_{0}^{1} x^{5} d x = \frac{1}{6}

= \frac{1}{4} + \frac{2}{5} + \frac{1}{6}

Vereinfache

\frac{1}{4} + \frac{2}{5} + \frac{1}{6} : \frac{49}{60}

= \frac{49}{60}
