integral of (x+5)/(x-5)

\int \frac{x + 5}{x - 5} d x

10 ln ∣ x - 5 ∣ + x + C

Solution steps

\int \frac{x + 5}{x - 5} d x

\frac{x + 5}{x - 5} = \frac{10}{x - 5} + 1

= \int \frac{10}{x - 5} + 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{10}{x - 5} d x + \int 1 d x

\int \frac{10}{x - 5} d x = 10 ln ∣ x - 5 ∣

\int 1 d x = x

= 10 ln ∣ x - 5 ∣ + x

Add a constant to the solution

= 10 ln ∣ x - 5 ∣ + x + C

\int - sin (3 x) (5 + cos (3 x))^{4} d x

\int \frac{1}{x ^{10}} d x

\int - x^{6} d x

\int 4 x^{\frac{1}{3}} - 6 x^{- \frac{1}{3}} d x

\int x - 9 d x
