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

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

ln ∣ x - 2 ∣ - \frac{4}{x - 2} + C

Solution steps

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

Expand

\frac{x + 2}{( x - 2 ) ^{2}} : \frac{x}{( x - 2 ) ^{2}} + \frac{2}{( x - 2 ) ^{2}}

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

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

\int \frac{2}{( x - 2 ) ^{2}} d x = - \frac{2}{x - 2}

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

Simplify

ln ∣ x - 2 ∣ - \frac{2}{x - 2} - \frac{2}{x - 2} : ln ∣ x - 2 ∣ - \frac{4}{x - 2}

= ln ∣ x - 2 ∣ - \frac{4}{x - 2}

Add a constant to the solution

= ln ∣ x - 2 ∣ - \frac{4}{x - 2} + C

\int \frac{2 x + 1}{( x ^{2} + 1 )} d x

\int 6 y - 1 d y

\int \frac{ln ( 6 x )}{x ^{3}} d x

\int 1 + 4 x^{3} (12 x^{2}) d x

\int (2 x - 3)^{6} d x
