Help understanding what limits are

  1. Jan 29, 2012 #1
    1. The problem statement, all variables and given/known data
    http://www4c.wolframalpha.com/Calculate/MSP/MSP18091a03ad70feibdhb300005da572897hebg236?MSPStoreType=image/gif&s=52&w=143&h=42 [Broken]

    2. Relevant equations
    lim x->2+ (x^2 - 3x + 2) / (x^3 - 4x)

    3. The attempt at a solution
    I plugged in 2 for x and it was 0/0 so then I divided each term by the highest power, which is x^3 but I still got 0/0. The answer is 1/8 but I don't know how to get it.

    Factor the numerator and denominator!
