\frac{3 + 16 x}{8 x - 4} : \frac{3}{8 x - 4} + \frac{16 x}{8 x - 4}

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}{8 x - 4} d x + \int \frac{16 x}{8 x - 4} d x

\int \frac{3}{8 x - 4} d x = \frac{3}{8} ln ∣ 8 x - 4 ∣

\int \frac{16 x}{8 x - 4} d x = 2 x - 1 + ln (4 ∣ 2 x - 1 ∣)

= \frac{3}{8} ln ∣ 8 x - 4 ∣ + 2 x - 1 + ln (4 ∣ 2 x - 1 ∣)
