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

= \int_{- 2}^{2} x^{4} + x^{2} 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_{- 2}^{2} x^{4} d x + \int_{- 2}^{2} x^{2} d x

\int_{- 2}^{2} x^{4} d x = \frac{64}{5}

\int_{- 2}^{2} x^{2} d x = \frac{16}{3}

= \frac{64}{5} + \frac{16}{3}

Vereinfache

\frac{64}{5} + \frac{16}{3} : \frac{272}{15}

= \frac{272}{15}
