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

2 + \frac{6}{x ^{4}}

Solution steps

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

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

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

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

\frac{d}{d x} (\frac{2}{x ^{3}}) = - \frac{6}{x ^{4}}

= 2 - (- \frac{6}{x ^{4}})

Simplify

= 2 + \frac{6}{x ^{4}}
