integral of (4x+2)/(x^2)

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

4 ln ∣ x ∣ - \frac{2}{x} + C

Solution steps

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

Expand

\frac{4 x + 2}{x ^{2}} : \frac{4}{x} + \frac{2}{x ^{2}}

= \int \frac{4}{x} + \frac{2}{x ^{2}} 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{2}{x ^{2}} d x

\int \frac{4}{x} d x = 4 ln ∣ x ∣

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

= 4 ln ∣ x ∣ - \frac{2}{x}

Add a constant to the solution

= 4 ln ∣ x ∣ - \frac{2}{x} + C

\frac{d}{d x} (arccot (e^{x}))

\int \frac{3 x ^{2}}{x ^{2} - 1} d x

\frac{d}{d x} (- 3 a sin (3 x) + 3 b cos (3 x))

x \to 5 + lim (\frac{2 x}{x - 5})

2 (\frac{2400}{x})
