2 x - 2*x + 3 ------------ 2 x
(x^2 - 2*x + 3)/x^2
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 derivative of a constant times a function is the constant times the derivative of the function.
Apply the power rule: goes to
So, the result is:
The result is:
To find :
Apply the power rule: goes to
Now plug in to the quotient rule:
Now simplify:
The answer is:
/ 2 \ -2 + 2*x 2*\x - 2*x + 3/ -------- - ---------------- 2 3 x x
/ / 2 \\ | 4*(-1 + x) 3*\3 + x - 2*x/| 2*|1 - ---------- + ----------------| | x 2 | \ x / ------------------------------------- 2 x
