Factoring question - generalized factoring in integers

  1. Nov 4, 2011 #1
    Hello, this is rather complicated to explain so bear with me.

    I was wondering about the coefficients of polynomials which are factorable in the integers, meaning polynomials which can be written as (x+a)(x+b) where a and b are integers.

    I had a curious idea about letting the x axis represent powers of x, and the y axis representing the value of each coefficient. Looking at a few plots of these coefficients makes me wonder several things. Most importantly though - is it useful to construct an axis based on powers of a variable?

    The polynomials are of the form x^2+(a+b)x+ab.
    In these graphs, the x axis - 0,1,2 are the powers of x, and y is the value of the coefficient.
    Each of these have a value of 1 for the coefficient of x^2, so all lines converge to (2,1).
    Each of the graphs has a constant factor a, and b is varied between -5:5, excluding 0.
    I've graphed for a=1,2 and 3.
    The graphs are basic and do not show which lines are for which polynomials, if I spend more time on it I'll make it do that.

    Does anyone know anything about or like this? any comments?
    Can I learn anything about factoring in integers from this?
