integral of (1/x-2/(x^2)+5/(x^3))

\int (\frac{1}{x} - \frac{2}{x ^{2}} + \frac{5}{x ^{3}}) d x

ln ∣ x ∣ + \frac{2}{x} - \frac{5}{2 x ^{2}} + C

Solution steps

\int \frac{1}{x} - \frac{2}{x ^{2}} + \frac{5}{x ^{3}} 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{1}{x} d x - \int \frac{2}{x ^{2}} d x + \int \frac{5}{x ^{3}} d x

\int \frac{1}{x} d x = ln ∣ x ∣

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

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

= ln ∣ x ∣ - (- \frac{2}{x}) - \frac{5}{2 x ^{2}}

Simplify

= ln ∣ x ∣ + \frac{2}{x} - \frac{5}{2 x ^{2}}

Add a constant to the solution

= ln ∣ x ∣ + \frac{2}{x} - \frac{5}{2 x ^{2}} + C
