r^2 -5r + 6 = (r-2)(r-3)
r^2 - 4 = (r-2)(r+2)
Cancel the (r-2)'s from the top and bottom.
Answer: (r-3)/(r+2)

Lots of ways to answer it.. but i'll give you the simplest. you're still doing long division on the problem. R^^2 -5R+6 inside the radical and R^^2 -4 outside.
simplest answer is 1 - [ (5R+2)/R^^2 - 4)]
but dont' know if thats the form you want it in.. you do have a remainder.

r Squared - 5r +6
------------------------ = (r-2)·(r-3) / [(r-2)·(r+2)] = (r-3)/(r+2)
r Squared - 4

What is the answer for r is not equal to +or- 2?
Presumably r can be any value except -2 or r.
So - inf
=(r-3)(r-2)/(r-2)(r+2) =(r-3)/(r+2) [r not = 2]

(r^2 - 5r + 6)/(r^2 - 4) =
(r-3) * (r-2) /((r-2)^2 =
(r-3)/(r-2) ans
