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

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

\frac{4}{5} x^{\frac{5}{2}} - 2 x + C

Solution steps

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

\int 2 x x d x = \frac{4}{5} x^{\frac{5}{2}}

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

= \frac{4}{5} x^{\frac{5}{2}} - 2 x

Add a constant to the solution

= \frac{4}{5} x^{\frac{5}{2}} - 2 x + C
