1. The problem statement, all variables and given/known data lim x→2 (4-(√18-x)) / (x-2) Note that the square root goes over the 18 AND the x, not just the 18. I don't know how to use the fancy mathematical notation on this forum and I have no idea where to go to find out how to use it. 2. Relevant equations There are absolutely NO relevant equations. ZERO! 3. The attempt at a solution I multiplied the numerator and the denominator by the conjugate of the numerator, because direct substitution would yield an indeterminate. However, after distributing, direct substitution of 2 still gave me an indeterminate. Here is my distribution (16-(18-x)) / (4x-x(√18-x)-8+(√18-x)) How can I further simplify this?
