\frac{x ^{\frac{3}{2}} - 2 x ^{6} - 1.2}{x} : x^{\frac{1}{2}} - 2 x^{5} - \frac{1.2}{x}

= \int x^{\frac{1}{2}} - 2 x^{5} - \frac{1.2}{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 x^{\frac{1}{2}} d x - \int 2 x^{5} d x - \int \frac{1.2}{x} d x

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

\int 2 x^{5} d x = \frac{x ^{6}}{3}

\int \frac{1.2}{x} d x = 1.2 ln ∣ x ∣

= \frac{2}{3} x^{\frac{3}{2}} - \frac{x ^{6}}{3} - 1.2 ln ∣ x ∣
