The method is based on d'Alembert's Lemma of algebra, which states that the absolute value of a polynomial assumes a minimum if and only if it is zero. Comparison of the method with other techniques for solving polynomial equations leads to the conclusion that, in addition to simplicity, ...
function conforms tocertain rules. We find Zeros of a polynomial function by setting the function equal to0. Examples 1-3 illustrate the concept of Zeros of polynomial functions using polynomial functions of degree two (quadratic functions). ...

coeff = polyfit(x,(y2-y1),100);% Perform a degree 100 polynomial curve fit on the difference between y1 and y2. possible_zeros = sort(unique(abs(roots(coeff)));% Roots of the polynomial curve fit - the absolute value is to convert complex roots, and the unique() function turns eac...
Note that for checking satisfiability we know what signs each polynomial is required to have which can be used to prune cases making the whole operation much more efficient. It is probably possible to do some pruning in the general case but I am not sure what the exact conditions would be ...
