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:
3 2 x 3*x - -------- + ----- 2 x - 1 (x - 1)
/ 2 \ | x 3*x | 2*x*|3 + --------- - ------| | 2 -1 + x| \ (-1 + x) / ---------------------------- -1 + x
/ 3 2 \ | x 3*x 3*x | 6*|1 - --------- - ------ + ---------| | 3 -1 + x 2| \ (-1 + x) (-1 + x) / -------------------------------------- -1 + x
