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

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

\frac{x ^{2}}{5} + 2 ln ∣ x ∣ + C

Solution steps

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

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

\int \frac{2}{x} d x = 2 ln ∣ x ∣

= \frac{x ^{2}}{5} + 2 ln ∣ x ∣

Add a constant to the solution

= \frac{x ^{2}}{5} + 2 ln ∣ x ∣ + C
