One also learns how to find roots of all quadratic polynomials, using square roots (arising from the discriminant) when necessary. The example is easy though, it is just one variable, while in my case I have 5, or actually 6 variables, so I am afraid that if FindRoot found some solution for all 5 (or 6) variables, it might not search for other alternatives. I appear to be getting relatively consistent solutions: FindRoot is very fast when I run it, but indeed gives slightly different results, but I also changed the equations: Thanks very much Marco!
