integral of (4+sqrt(x)+x)/x

\int \frac{4 + x + x}{x} d x

4 ln ∣ x ∣ + 2 x + x + C

Solution steps

\int \frac{4 + x + x}{x} d x

Expand

\frac{4 + x + x}{x} : \frac{4}{x} + \frac{1}{x} + 1

= \int \frac{4}{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{4}{x} d x + \int \frac{1}{x} d x + \int 1 d x

\int \frac{4}{x} d x = 4 ln ∣ x ∣

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

\int 1 d x = x

= 4 ln ∣ x ∣ + 2 x + x

Add a constant to the solution

= 4 ln ∣ x ∣ + 2 x + x + C

\frac{\partial}{\partial y} (2 x y^{2} + y)

f (x) = (\frac{x}{x ^{2} + 1})^{2}

\frac{d y}{d x} + y = x e^{- x} + 1

n = 0 \sum \infty \frac{1}{n ( n + 2 )}

x \to 5 lim (x^{2} - 25)
