Another limit problem

  1. Feb 25, 2008 #1
    lim sqrt(x^2 + x) - x as x approaches infinity

    Not sure what I need to do. I tried to make it into a fraction so I could apply L'Hospital's rule but I didnt' get anywhere with that. Any ideas?

    Yeah like arildno suggested you need to rationalize the expression by multiplying with what post #2 suggests!
