integral of (1-2x)/(sqrt(x))

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

2 x - \frac{4}{3} x^{\frac{3}{2}} + C

Solution steps

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

Expand

\frac{1 - 2 x}{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 = \frac{4}{3} x^{\frac{3}{2}}

= 2 x - \frac{4}{3} x^{\frac{3}{2}}

Add a constant to the solution

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

\int x (4 + 3 x^{2})^{7} d x

\int sin^{3} (m x) d x

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

\int x e^{- n x} d x

\int \frac{( 2 x + 1 )}{x ^{2} + 2 x + 5} d x
