2 x + x - 6 ---------- x - 1
(x^2 + x - 6)/(x - 1)
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
Apply the power rule: goes to
The result is:
To find :

The result is:
Now plug in to the quotient rule:
Now simplify:
The answer is:
2
1 + 2*x x + x - 6
