integral of (x+2)/(x^2-4x+4)

\int \frac{x + 2}{x ^{2} - 4 x + 4} d x

- \frac{x}{x - 2} + ln ∣ x - 2 ∣ - \frac{2}{x - 2} + C

Solution steps

\int \frac{x + 2}{x ^{2} - 4 x + 4} d x

Expand

\frac{x + 2}{x ^{2} - 4 x + 4} : \frac{x}{x ^{2} - 4 x + 4} + \frac{2}{x ^{2} - 4 x + 4}

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{x}{x ^{2} - 4 x + 4} d x + \int \frac{2}{x ^{2} - 4 x + 4} d x

\int \frac{x}{x ^{2} - 4 x + 4} d x = - \frac{x}{x - 2} + ln ∣ x - 2 ∣

\int \frac{2}{x ^{2} - 4 x + 4} d x = - \frac{2}{x - 2}

= - \frac{x}{x - 2} + ln ∣ x - 2 ∣ - \frac{2}{x - 2}

Add a constant to the solution

= - \frac{x}{x - 2} + ln ∣ x - 2 ∣ - \frac{2}{x - 2} + C

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

\int (2 x^{2} + 7 x^{- 2}) d x

\int c e^{- \frac{x}{2}} d x

\int e^{x} + 6 x^{5} d x
