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

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

- \frac{2}{x} + \frac{2}{x} + C

Solution steps

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

Expand

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

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

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

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

= - \frac{2}{x} - (- \frac{2}{x})

Simplify

= - \frac{2}{x} + \frac{2}{x}

Add a constant to the solution

= - \frac{2}{x} + \frac{2}{x} + C

\int (3 x + 1)^{6} d x

\int 6 x^{- \frac{6}{7}} d x

\int 2 x^{3} ln (x^{2} + 1) d x

\int (3 x^{2} - 5)^{4} x d x

\int t - t^{2} d t
