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

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

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

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

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

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

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

Add a constant to the solution

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

\frac{\partial}{\partial x} (cos (2 y - 3 x))

\int (2 x + 1) ln (x + 1) d x

\frac{\partial}{\partial x} (\frac{1}{1 + e})

\int \frac{x}{2 y ^{4}} d x

\frac{d}{d x} (\frac{3 sin ( x )}{2 + cos ( x )})
