integral of (2x-3)/x

Solution

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

Solution

2 x - 3 ln ∣ x ∣ + C

Solution steps

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

Expand

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

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

Apply the Sum Rule:

\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{3}{x} d x

\int 2 d x = 2 x

\int \frac{3}{x} d x = 3 ln ∣ x ∣

= 2 x - 3 ln ∣ x ∣

Add a constant to the solution

= 2 x - 3 ln ∣ x ∣ + C
