(d^2}{dx^2}(\frac{4x^3+6)/x)

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

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

Solution steps

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

\frac{d}{d x} (\frac{4 x ^{3} + 6}{x}) = \frac{8 x ^{3} - 6}{x ^{2}}

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

\frac{d}{d x} (\frac{8 x ^{3} - 6}{x ^{2}}) = \frac{4 ( 2 x ^{3} + 3 )}{x ^{3}}

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