integral of x/(2-x)

Solution

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

Solution

- 2 ln ∣ 2 - x ∣ - x + C

Solution steps

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

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

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

\int \frac{2}{2 - x} d x = - 2 ln ∣ 2 - x ∣

\int 1 d x = x

= - 2 ln ∣ 2 - x ∣ - x

Add a constant to the solution

= - 2 ln ∣ 2 - x ∣ - x + C
