The derivative of a quotient is:
(bottom times deriv of the top) - (top times deriv of bottom) all divided by (bottom squared).
I want you to know that after 51 years, I not only remember that, but I know how to use it too.
Derivative of (25x + 4) / (x+4) with respect to 'x' =
[ (x+4)(25) - (25x+4) ] / (x+4)2
= (25x + 100 - 25x - 4) / (x+4)2
= 96 / (x2 + 8x + 16)
There you go. We not only told you how to do it, we also did it for you.
