integral of (x+5)/(x-3)

\int \frac{x + 5}{x - 3} d x

8 ln ∣ x - 3 ∣ + x + C

Solution steps

\int \frac{x + 5}{x - 3} d x

\frac{x + 5}{x - 3} = \frac{8}{x - 3} + 1

= \int \frac{8}{x - 3} + 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{8}{x - 3} d x + \int 1 d x

\int \frac{8}{x - 3} d x = 8 ln ∣ x - 3 ∣

\int 1 d x = x

= 8 ln ∣ x - 3 ∣ + x

Add a constant to the solution

= 8 ln ∣ x - 3 ∣ + x + C

\int - 300 v + 360 d v

\int (3 x - 7)^{5} d x

\frac{6}{x ^{2}}

\int (5 - 2 x)^{10} d x

\int 4 x 2 x^{2} + 3 d x
