integral of 2/5-9/x

Solution

\int \frac{2}{5} - \frac{9}{x} d x

Solution

\frac{2}{5} x - 9 ln ∣ x ∣ + C

Solution steps

\int \frac{2}{5} - \frac{9}{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 \frac{2}{5} d x - \int \frac{9}{x} d x

\int \frac{2}{5} d x = \frac{2}{5} x

\int \frac{9}{x} d x = 9 ln ∣ x ∣

= \frac{2}{5} x - 9 ln ∣ x ∣

Add a constant to the solution

= \frac{2}{5} x - 9 ln ∣ x ∣ + C
