integral of ((1+sqrt(x)+x)/x)

\int (\frac{1 + x + x}{x}) d x

ln ∣ x ∣ + 2 x + x + C

Solution steps

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

Expand

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

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

\int \frac{1}{x} d x = ln ∣ x ∣

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

\int 1 d x = x

= ln ∣ x ∣ + 2 x + x

Add a constant to the solution

= ln ∣ x ∣ + 2 x + x + C

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

x = - y, x = 2 - y^{2}

x \to 6 lim (g (x))

\int \frac{1}{x ^{2} 7 - 16 x ^{2}} d x

\frac{\partial}{\partial y} (1 - x^{2} - y^{2})
