Homework Help: Factoring a polynomial

  1. Jan 21, 2010 #1
    1. The problem statement, all variables and given/known data

    7X2(X - 2) - (X - 2)

    2. The attempt at a solution

    Ok, this is really simple but for some reason I can't figure out why the answer has to be (7X2 - 1)(X - 2)

    The process is that I have to divide both parts by (X - 2). However, if I do that, I only get 7X2 - 1. Where does that (X - 2) come from for the final answer?

    Re: Factoring

    you don't divide it, you factor it out.

    you'll be left with

    {x-2}{7x2(1)-1(1)}

    understand?
