[sage-support] recurrence relation for a system of simultaneous equations

I have a system of polynomial equations with rational coefficients and I have one rational solution. I am trying to find a recurrence relation that will allow me to generate additional rational solutions. The equations are: A6x0^2+A5x1^2+A4x2^2+A3x0x1+A2x0x2+A1x1x2+A0=0 (a)
