Re: [math-fun] What does it mean?

Yes, for |x| < 1, the values of x for which the series converges, it's an identity: 4x^4 + 7x^2 - x + 1 = (x+1)[1 - 2x + 9x^2 - 9x^3 + 13x^4/(1+x)] On Tue, 22 Jun 2004, Jon Perry wrote:

If I consider a polynomial in integers, e.g. 4x^4 + 7x^2 - x + 1, then I can say that this is;

(x+1)[1 - 2x + 9x^2 - 9x^3 + 13x^4 - 13x^5 + 13x^6 - ...]

Does this mean anything?
