Apply the quotient rule, which is:
and .
To find :
Apply the power rule: goes to
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:
Now simplify:
The answer is:
2 x 2*x - -------- + ----- 2 x - 1 (x - 1)
/ 2 \ | x 2*x | 2*|1 + --------- - ------| | 2 -1 + x| \ (-1 + x) / -------------------------- -1 + x
/ 2 \ | x 2*x | 6*|-1 - --------- + ------| | 2 -1 + x| \ (-1 + x) / --------------------------- 2 (-1 + x)
