integral of (-4n-2)/((n-3)^2)

\int \frac{- 4 n - 2}{( n - 3 ) ^{2}} d n

- 4 ln ∣ n - 3 ∣ + \frac{14}{n - 3} + C

Solution steps

\int \frac{- 4 n - 2}{( n - 3 ) ^{2}} d n

Expand

\frac{- 4 n - 2}{( n - 3 ) ^{2}} : - \frac{4 n}{( n - 3 ) ^{2}} - \frac{2}{( n - 3 ) ^{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{4 n}{( n - 3 ) ^{2}} d n - \int \frac{2}{( n - 3 ) ^{2}} d n

\int \frac{4 n}{( n - 3 ) ^{2}} d n = 4 (ln ∣ n - 3 ∣ - \frac{3}{n - 3})

\int \frac{2}{( n - 3 ) ^{2}} d n = - \frac{2}{n - 3}

= - 4 (ln ∣ n - 3 ∣ - \frac{3}{n - 3}) - (- \frac{2}{n - 3})

Simplify

- 4 (ln ∣ n - 3 ∣ - \frac{3}{n - 3}) - (- \frac{2}{n - 3}) : - 4 ln ∣ n - 3 ∣ + \frac{14}{n - 3}

= - 4 ln ∣ n - 3 ∣ + \frac{14}{n - 3}

Add a constant to the solution

= - 4 ln ∣ n - 3 ∣ + \frac{14}{n - 3} + C

\int cos^{2} (x) cos (x) d x

\int t sin (4 t) d t

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

\int \frac{4 x ^{2} - 2 x + 1}{x ^{3} + x} d x

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