integral of ((3x-2)^2)/(sqrt(x))

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

\frac{18}{5} x^{\frac{5}{2}} - 8 x^{\frac{3}{2}} + 8 x + C

Solution steps

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

Expand

\frac{( 3 x - 2 ) ^{2}}{x} : 9 x^{\frac{3}{2}} - 12 x + \frac{4}{x}

= \int 9 x^{\frac{3}{2}} - 12 x + \frac{4}{x} 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 9 x^{\frac{3}{2}} d x - \int 12 x d x + \int \frac{4}{x} d x

\int 9 x^{\frac{3}{2}} d x = \frac{18}{5} x^{\frac{5}{2}}

\int 12 x d x = 8 x^{\frac{3}{2}}

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

= \frac{18}{5} x^{\frac{5}{2}} - 8 x^{\frac{3}{2}} + 8 x

Add a constant to the solution

= \frac{18}{5} x^{\frac{5}{2}} - 8 x^{\frac{3}{2}} + 8 x + C

\int (1 - x)^{b} d x

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

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

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

\int x^{3} + 3 x^{2} d x
