Homework Help: Calculate limit Using Limit Laws

  1. Nov 28, 2009 #1
    1. The problem statement, all variables and given/known data

    Calculate limit Using Limit Laws

    2. Relevant equations

    Lim x+2/X^3+8 as X-->(-2)

    3. The attempt at a solution

    Ok so, I'm a little stumped as to what trick I need to pull out of the bag for this one. Obviously the function goes to 0/0, but I cant seem to factor anything out of the denominator to make it work. But I do know that x to the third and 8 have a cubed root. Any hints or suggestions as to what to do?

    What are the limit laws.

    Factor x^3 + 8 = ?
    And simplify
