integral of (x+5)/(x-4)

Lösung

\int \frac{x + 5}{x - 4} d x

9 ln ∣ x - 4 ∣ + x + C

Schritte zur Lösung

\int \frac{x + 5}{x - 4} d x

\frac{x + 5}{x - 4} = \frac{9}{x - 4} + 1

= \int \frac{9}{x - 4} + 1 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{9}{x - 4} d x + \int 1 d x

\int \frac{9}{x - 4} d x = 9 ln ∣ x - 4 ∣

\int 1 d x = x

= 9 ln ∣ x - 4 ∣ + x
