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

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

2 x - x^{2} + C

Solution steps

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

Expand

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

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

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

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

= 2 x - x^{2}

Add a constant to the solution

= 2 x - x^{2} + C

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

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

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

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