integral of ((6+sqrt(x)+x)/x)

\int (\frac{6 + x + x}{x}) d x

6 ln ∣ x ∣ + 2 x + x + C

Solution steps

\int \frac{6 + x + x}{x} d x

Expand

\frac{6 + x + x}{x} : \frac{6}{x} + \frac{1}{x} + 1

= \int \frac{6}{x} + \frac{1}{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{6}{x} d x + \int \frac{1}{x} d x + \int 1 d x

\int \frac{6}{x} d x = 6 ln ∣ x ∣

\int \frac{1}{x} d x = 2 x

\int 1 d x = x

= 6 ln ∣ x ∣ + 2 x + x

Add a constant to the solution

= 6 ln ∣ x ∣ + 2 x + x + C

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

\int 2 - \frac{1}{x ^{2}} d x

\int cos (x^{2} - 2 x) (x - 1) d x

\int (x - 2) sin (x) d x

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