(d^2)/(dx^2)(((x-3)(x^2+3x+9))/(x^3))

\frac{d ^{2}}{d x ^{2}} (\frac{( x - 3 ) ( x ^{2} + 3 x + 9 )}{x ^{3}})

- \frac{324}{x ^{5}}

Solution steps

\frac{d ^{2}}{d x ^{2}} (\frac{( x - 3 ) ( x ^{2} + 3 x + 9 )}{x ^{3}})

\frac{d}{d x} (\frac{( x - 3 ) ( x ^{2} + 3 x + 9 )}{x ^{3}}) = \frac{81}{x ^{4}}

= \frac{d}{d x} (\frac{81}{x ^{4}})

\frac{d}{d x} (\frac{81}{x ^{4}}) = - \frac{324}{x ^{5}}

= - \frac{324}{x ^{5}}
