derivative of

\frac{- 2}{x ^{2}}

\frac{4}{x ^{3}}

Solution steps

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

Simplify

\frac{- 2}{x ^{2}} : - \frac{2}{x ^{2}}

= \frac{d}{d x} (- \frac{2}{x ^{2}})

Take the constant out:

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

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

Apply exponent rule:

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

= - 2 \frac{d}{d x} (x^{- 2})

Apply the Power Rule:

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

= - 2 (- 2 x^{- 2 - 1})

Simplify

- 2 (- 2 x^{- 2 - 1}) : \frac{4}{x ^{3}}

= \frac{4}{x ^{3}}

\frac{( x ^{2} + 1 )}{( x - 2 )}

ln (x + 2)

e^{4} x

4 sin^{2} (x^{2})

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