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

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

ln ∣ x ∣ + \frac{2}{x} + C

Solution steps

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

Expand

\frac{x - x}{x ^{2}} : \frac{1}{x} - \frac{1}{x ^{\frac{3}{2}}}

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

\int \frac{1}{x} d x = ln ∣ x ∣

\int \frac{1}{x ^{\frac{3}{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

\int \frac{( ln ( x ) - 1 ) ln ( x )}{x} d x

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

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

\int x (3 x - 2) d x

\int - x^{2} e^{2 x^{3}} d x
