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

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

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

Solution steps

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

Expand

\frac{x + 2}{x} : x + \frac{2}{x}

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

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

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

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

Add a constant to the solution

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

x \to 0 lim (\frac{3 ^{x} - 2 ^{x}}{x})

\frac{\partial}{\partial x} (\frac{x}{x + 3})

f (x) = \frac{x}{x ^{2} - 1}

\frac{d ^{2} y}{d x ^{2}} - 2 \frac{d y}{d x} - 8 y = 0

\int \frac{9}{x - 4} d x
