Does my answer look correct?

Find the derivative.

11, y= (e^3-e)(e+5)/6e

my work:

((6e)(4e^3 + 15e^2 - 2e - 5) - (6)(e^4 + 5e^3 - e^2 - 5e))/ (6e)^2

Multiplied/divided everything through

My answer:

(10e^2 + 30e - 3)/ 18

I cant follow your work:

I assume e is a derivative.

(e^3-e)(e+5)/6e

1/6e * (e^4 + 5e^3 -e^2 - 5e)

1/6 * (e^3 + 5e^2 -e-5 )

derivative:

dy/de = 1/6 (3e^2+10e -1)

check my work.
