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

\frac{x ^{2}}{2} - 3

Solution steps

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

Apply the Sum/Difference Rule:

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

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

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

\frac{d}{d x} (3 x) = 3

= \frac{x ^{2}}{2} - 3
