\frac{d}{d x} (\frac{8 x ^{3} - 6}{x ^{2}})

\frac{4 ( 2 x ^{3} + 3 )}{x ^{3}}

Solution steps

\frac{d}{d x} (\frac{8 x ^{3} - 6}{x ^{2}})

Apply the Quotient Rule:

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

= \frac{\frac{d}{d x} ( 8 x ^{3} - 6 ) x ^{2} - \frac{d}{d x} ( x ^{2} ) ( 8 x ^{3} - 6 )}{( x ^{2} ) ^{2}}

\frac{d}{d x} (8 x^{3} - 6) = 24 x^{2}

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

= \frac{24 x ^{2} x ^{2} - 2 x ( 8 x ^{3} - 6 )}{( x ^{2} ) ^{2}}

Simplify

\frac{24 x ^{2} x ^{2} - 2 x ( 8 x ^{3} - 6 )}{( x ^{2} ) ^{2}} : \frac{4 ( 2 x ^{3} + 3 )}{x ^{3}}

= \frac{4 ( 2 x ^{3} + 3 )}{x ^{3}}
