integral of-2x^{-2}

Solution

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

Solution

\frac{2}{x} + C

Solution steps

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

Take the constant out:

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

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

Apply the Power Rule

: - \frac{1}{x}

= - 2 (- \frac{1}{x})

Simplify

- 2 (- \frac{1}{x}) : \frac{2}{x}

= \frac{2}{x}

Add a constant to the solution

= \frac{2}{x} + C
