Hi,
Q1.
lim (x = infinity) { (X^2 +5x - 6)/(4x^2 +x -8) }
Q2.
lim (x = infinity) { x^2/(x+5) - x }
i know how to find limits of functions, but i dont know how to do it when x is infinity, please explain,
thanks

When you have a limit that looks like 0/0 or Infinity/Infinity thats when you use L'Hopital's rule.
For the first one you can use the rule immediately. For the second one you have to get it in the form Infinity/Infinity so you get a common denominator and it turns into -5x/(x+5), and then use the rule.
