derivative of

f (x) = \frac{6 x - 1}{x ^{3}}

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

Solution steps

\frac{d}{d x} (\frac{6 x - 1}{x ^{3}})

Apply the Quotient Rule:

(\frac{f}{g})^{'} = \frac{f ^{'} \cdot g - g ^{'} \cdot f}{g ^{2}}

= \frac{\frac{d}{d x} ( 6 x - 1 ) x ^{3} - \frac{d}{d x} ( x ^{3} ) ( 6 x - 1 )}{( x ^{3} ) ^{2}}

\frac{d}{d x} (6 x - 1) = 6

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

= \frac{6 x ^{3} - 3 x ^{2} ( 6 x - 1 )}{( x ^{3} ) ^{2}}

Simplify

\frac{6 x ^{3} - 3 x ^{2} ( 6 x - 1 )}{( x ^{3} ) ^{2}} : \frac{3 ( - 4 x + 1 )}{x ^{4}}

= \frac{3 ( - 4 x + 1 )}{x ^{4}}
