1. The problem statement, all variables and given/known data What is the limit as x goes to positive infinity of: (4x2+3x+8)/(6x2+5x-7)? 2. Relevant equations 3. The attempt at a solution Usually I would factor the top and bottom and see if something cancels, but that doesn't work here. Also l'hopital rule doesn't work. I thought the answer would be one because substituting x for infinity gives infinity/infinity=1. But apparently that's not the correct answer. Help?
