Apply the quotient rule, which is:
and .
To find :
Differentiate term by term:
The derivative of the constant is zero.
Apply the power rule: goes to
The result is:

The result is:
Now plug in to the quotient rule:
The answer is:
1 x + 5 ----- - -------- x - 1 2 (x - 1)
/ 5 + x \ 2*|-1 + ------| \ -1 + x/ --------------- 2 (-1 + x)
/ 5 + x \ 6*|1 - ------| \ -1 + x/ -------------- 3 (-1 + x)
