\frac{d}{d x} (\frac{- 4}{x})

\frac{4}{x ^{2}}

Solution steps

\frac{d}{d x} (\frac{- 4}{x})

Simplify

\frac{- 4}{x} : - \frac{4}{x}

= \frac{d}{d x} (- \frac{4}{x})

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= - 4 \frac{d}{d x} (\frac{1}{x})

Apply exponent rule:

\frac{1}{a} = a^{- 1}

= - 4 \frac{d}{d x} (x^{- 1})

Apply the Power Rule:

\frac{d}{d x} (x^{a}) = a \cdot x^{a - 1}

= - 4 (- 1 \cdot x^{- 1 - 1})

Simplify

- 4 (- 1 \cdot x^{- 1 - 1}) : \frac{4}{x ^{2}}

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