integral of 5/x-3/(x^2)

\int \frac{5}{x} - \frac{3}{x ^{2}} d x

5 ln ∣ x ∣ + \frac{3}{x} + C

Solution steps

\int \frac{5}{x} - \frac{3}{x ^{2}} 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{5}{x} d x - \int \frac{3}{x ^{2}} d x

\int \frac{5}{x} d x = 5 ln ∣ x ∣

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

= 5 ln ∣ x ∣ - (- \frac{3}{x})

Simplify

= 5 ln ∣ x ∣ + \frac{3}{x}

Add a constant to the solution

= 5 ln ∣ x ∣ + \frac{3}{x} + C
