Find StartFraction dy Over dx EndFraction for y equals StartFraction negative 5 x cubed minus 5 x squared plus 3 Over negative 5 x Superscript 4 Baseline plus 2 EndFraction . Do not simplify.

Step-by-step explanation:

Given:

We are required to find the derivative of y with respect to x,   .

We apply the quotient rule:

For a fractional expression,

Since we are asked not to simplify, we simply leave our answer in the substituted form above.

b

step-by-step explanation:
