integral of (8+x)/x

Solution

\int \frac{8 + x}{x} d x

Solution

8 ln ∣ x ∣ + x + C

Solution steps

\int \frac{8 + x}{x} d x

Expand

\frac{8 + x}{x} : \frac{8}{x} + 1

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

\int \frac{8}{x} d x = 8 ln ∣ x ∣

\int 1 d x = x

= 8 ln ∣ x ∣ + x

Add a constant to the solution

= 8 ln ∣ x ∣ + x + C
