1 1*------- 2 x + 25
d / 1 \ --|1*-------| dx| 2 | \ x + 25/
Apply the quotient rule, which is:
and .
To find :
The derivative of the constant is zero.
To find :
Differentiate term by term:
The derivative of the constant is zero.
Apply the power rule: goes to
The result is:
Now plug in to the quotient rule:
The answer is:
-2*x ---------- 2 / 2 \ \x + 25/
/ 2 \ | 4*x | 2*|-1 + -------| | 2| \ 25 + x / ---------------- 2 / 2\ \25 + x /
/ 2 \ | 2*x | -24*x*|-1 + -------| | 2| \ 25 + x / -------------------- 3 / 2\ \25 + x /
