\frac{2 - 3 x ^{2}}{x ^{3}} : \frac{2}{x ^{3}} - \frac{3}{x}

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

\int \frac{2}{x ^{3}} d x = - \frac{1}{x ^{2}}

\int \frac{3}{x} d x = 3 ln ∣ x ∣

= - \frac{1}{x ^{2}} - 3 ln ∣ x ∣
