\frac{2 x ^{2} - 4}{x ^{2} ( x - 2 )} : \frac{2 x ^{2}}{x ^{2} ( x - 2 )} - \frac{4}{x ^{2} ( x - 2 )}

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 ^{2}}{x ^{2} ( x - 2 )} d x - \int \frac{4}{x ^{2} ( x - 2 )} d x

\int \frac{2 x ^{2}}{x ^{2} ( x - 2 )} d x = 2 ln ∣ x - 2 ∣

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

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

Vereinfache

= ln ∣ x - 2 ∣ + ln ∣ x ∣ - \frac{2}{x}
