\frac{- 5 x ^{2} - 32 x + 80}{( x ^{2} - 5 x ) ^{2}}

\frac{- 5 x ^{2} - 32 x + 80}{x ^{4} - 10 x ^{3} + 25 x ^{2}}

求解步骤

\frac{- 5 x ^{2} - 32 x + 80}{( x ^{2} - 5 x ) ^{2}}

(x^{2} - 5 x)^{2} = x^{4} - 10 x^{3} + 25 x^{2}

= \frac{- 5 x ^{2} - 32 x + 80}{x ^{4} - 10 x ^{3} + 25 x ^{2}}

\frac{d ^{2}}{d x ^{2}} ((y) (- 4 x + 9)^{2})
