\frac{12 x ^{4} + 3 x ^{2} + 6 a x}{x} : \frac{12 x ^{4}}{x} + \frac{3 x ^{2}}{x} + \frac{6 a x}{x}

Wende die Summenregel an:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \frac{1}{2} (\int \frac{12 x ^{4}}{x} d x + \int \frac{3 x ^{2}}{x} d x + \int \frac{6 a x}{x} d x)

\int \frac{12 x ^{4}}{x} d x = 3 x^{4}

\int \frac{3 x ^{2}}{x} d x = \frac{3 x ^{2}}{2}

\int \frac{6 a x}{x} d x = 6 a x

= \frac{1}{2} (3 x^{4} + \frac{3 x ^{2}}{2} + 6 a x)
