I don't know how to format, sorry...
"Find the limit, if it exists"
Limit (as x approaches 2): (x^2 - x +6)/(x-2)
I used the quadratic formula to try to find values for the numerator, but one ends up with 1 plus or minus the square root of -23 divided by two. Obviously, negative numbers don't have real square roots, so is it safe to say there is no limit to this equation? Thanks...
