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

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

8 x - \frac{8}{3} x^{\frac{3}{2}} + \frac{2}{5} x^{\frac{5}{2}} + C

Solution steps

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

Expand

\frac{( 2 - x ) ^{2}}{x} : \frac{4}{x} - 4 x + x^{\frac{3}{2}}

= \int \frac{4}{x} - 4 x + 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{4}{x} d x - \int 4 x d x + \int x^{\frac{3}{2}} d x

\int \frac{4}{x} d x = 8 x

\int 4 x d x = \frac{8}{3} x^{\frac{3}{2}}

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

= 8 x - \frac{8}{3} x^{\frac{3}{2}} + \frac{2}{5} x^{\frac{5}{2}}

Add a constant to the solution

= 8 x - \frac{8}{3} x^{\frac{3}{2}} + \frac{2}{5} x^{\frac{5}{2}} + C

\int x^{9} sin (x^{10}) d x

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

\int \frac{2}{( x - 7 ) ( x - 5 )} d x

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

\int sec (x) d tan (x) d x
