1. The problem statement, all variables and given/known data lim x→2 ((sqrt(6-x)-2) / (sqrt(3-x) - 1) 2. Relevant equations none 3. The attempt at a solution My daughter's grade 12 mathematics class is not yet using l'hopital, yet this question has been posed as a practice question. I can solve it readily with l'hopital, however without it I'm stumped. When I attempt by multiplying numerator and denominator by (sqrt(3-x) +1 ) predictably I get 0 for my troubles.
