Multipliziere aus

(3 x^{2} + 6)^{2} : 9 x^{4} + 36 x^{2} + 36

= \int 9 x^{4} + 36 x^{2} + 36 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 9 x^{4} d x + \int 36 x^{2} d x + \int 36 d x

\int 9 x^{4} d x = \frac{9 x ^{5}}{5}

\int 36 x^{2} d x = 12 x^{3}

\int 36 d x = 36 x

= \frac{9 x ^{5}}{5} + 12 x^{3} + 36 x

Füge eine Konstante zur Lösung hinzu

= \frac{9 x ^{5}}{5} + 12 x^{3} + 36 x + C
