Homework Help: Very simple Simplification Question

  1. Feb 13, 2008 #1
    1. The problem statement, all variables and given/known data

    (2x^2+4x+2)/x+1 = l

    Simplify the equation for l. I do not want to solve it, just simplify.

    2. Relevant equations

    3. The attempt at a solution

    I actually reduced the equation this far already, and the back of the book says I have gotten the equation right up to this point, but then it gives the answer, but not the steps to get there. The ANSWER: 2(x+1) .... I do not understand how to get that .

    can you simplify (x^2+2x+1) further? (think of perfect squares)
