integral of-2x^{-1/2}

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

- 4 x^{\frac{1}{2}} + C

Solution steps

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

Apply the Power Rule

= - 2 \cdot 2 x^{\frac{1}{2}}

Simplify

= - 4 x^{\frac{1}{2}}

Add a constant to the solution

= - 4 x^{\frac{1}{2}} + C
