integral of 1/(sqrt(x)(\sqrt{x)-2)}

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

2 ln x - 2 + C

Solution steps

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

Apply u-substitution

= \int \frac{2}{u - 2} d u

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 2 \cdot \int \frac{1}{u - 2} d u

Apply u-substitution

= 2 \cdot \int \frac{1}{v} d v

Use the common integral:

\int \frac{1}{v} d v = ln (∣ v ∣)

= 2 ln ∣ v ∣

Substitute back

= 2 ln x - 2

Add a constant to the solution

= 2 ln x - 2 + C
