\frac{2 + x + x}{x} : \frac{2}{x} + 1 + \frac{1}{x}

= \int \frac{2}{x} + 1 + \frac{1}{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} d x + \int 1 d x + \int \frac{1}{x} d x

\int \frac{2}{x} d x = 2 ln ∣ x ∣

\int 1 d x = x

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

= 2 ln ∣ x ∣ + x + 2 x
