integral of 3/x-2/(x^2)

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

3 ln ∣ x ∣ + \frac{2}{x} + C

Solution steps

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

\int \frac{3}{x} d x = 3 ln ∣ x ∣

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

= 3 ln ∣ x ∣ - (- \frac{2}{x})

Simplify

= 3 ln ∣ x ∣ + \frac{2}{x}

Add a constant to the solution

= 3 ln ∣ x ∣ + \frac{2}{x} + C

\int x^{2} (x^{2} - 3) d x

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

- 0.4 x^{2}

\int (\frac{7 x ^{6} - 8 x ^{4} + 9 x ^{3}}{2 x ^{2}}) d x

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