integral of (-2/x)

\int (- \frac{2}{x}) d x

- 2 ln ∣ x ∣ + C

Solution steps

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

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

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

Use the common integral:

\int \frac{1}{x} d x = ln (∣ x ∣)

= - 2 ln ∣ x ∣

Add a constant to the solution

= - 2 ln ∣ x ∣ + C

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

\int x^{3} e^{x^{4} + 1} d x

\int \frac{9 x ^{2} + x}{( 12 x ^{3} + 2 x ^{2} ) ^{2}} d x

\int \frac{5 e ^{- \frac{1}{x}}}{x ^{2}} d x
