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

Solution

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

Solution

ln ∣ x ∣ + \frac{2}{x} + C

Solution steps

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

Expand

\frac{x - 2}{x ^{2}} : \frac{1}{x} - \frac{2}{x ^{2}}

= \int \frac{1}{x} - \frac{2}{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{1}{x} d x - \int \frac{2}{x ^{2}} d x

\int \frac{1}{x} d x = ln ∣ x ∣

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

= ln ∣ x ∣ - (- \frac{2}{x})

Simplify

= ln ∣ x ∣ + \frac{2}{x}

Add a constant to the solution

= ln ∣ x ∣ + \frac{2}{x} + C
