integral of 4/(x^3)+2/x

\int \frac{4}{x ^{3}} + \frac{2}{x} d x

- \frac{2}{x ^{2}} + 2 ln ∣ x ∣ + C

Solution steps

\int \frac{4}{x ^{3}} + \frac{2}{x} 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 ^{3}} d x + \int \frac{2}{x} d x

\int \frac{4}{x ^{3}} d x = - \frac{2}{x ^{2}}

\int \frac{2}{x} d x = 2 ln ∣ x ∣

= - \frac{2}{x ^{2}} + 2 ln ∣ x ∣

Add a constant to the solution

= - \frac{2}{x ^{2}} + 2 ln ∣ x ∣ + C
