i know how to solve limits, but i have trouble seeing if i can factor anymore or if the limit just doesn't exist, which is the case with the next few questions 1. The problem statement, all variables and given/known data 1/(sqrt(x)-2) - 4/(x-4) 2. Relevant equations 3. The attempt at a solution this is what i have now, i dont think i can do anything else, but im probably wrong. And i have written that the limit doesn't exist. x-4sqrt(x)+4/(x-4)(sqrt(x)-2) and sorry if the equation is written the wrong way or anything, with the square roots and everything!
