\frac{3 x - 2}{2 x - 1} : \frac{3 x}{2 x - 1} - \frac{2}{2 x - 1}

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

\int \frac{3 x}{2 x - 1} d x = \frac{3}{4} (2 x - 1 + ln ∣ 2 x - 1 ∣)

\int \frac{2}{2 x - 1} d x = ln ∣ 2 x - 1 ∣

= \frac{3}{4} (2 x - 1 + ln ∣ 2 x - 1 ∣) - ln ∣ 2 x - 1 ∣

Vereinfache

\frac{3}{4} (2 x - 1 + ln ∣ 2 x - 1 ∣) - ln ∣ 2 x - 1 ∣ : \frac{3}{2} x - \frac{3}{4} - \frac{1}{4} ln ∣ 2 x - 1 ∣

= \frac{3}{2} x - \frac{3}{4} - \frac{1}{4} ln ∣ 2 x - 1 ∣
