integral of ((4x+3)/(2x+5))

Lösung

\int (\frac{4 x + 3}{2 x + 5}) d x

2 x - \frac{7}{2} ln ∣ 2 x + 5 ∣ + C

Schritte zur Lösung

\int \frac{4 x + 3}{2 x + 5} d x

Lange Division

\frac{4 x + 3}{2 x + 5} : 2 - \frac{7}{2 x + 5}

= \int 2 - \frac{7}{2 x + 5} 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 2 d x - \int \frac{7}{2 x + 5} d x

\int 2 d x = 2 x

\int \frac{7}{2 x + 5} d x = \frac{7}{2} ln ∣ 2 x + 5 ∣

= 2 x - \frac{7}{2} ln ∣ 2 x + 5 ∣
