I am solving some simultaneous equations and getting four results because the solution contains two square roots - produced because some of the equations to solve are of the form x^2 = y^2 + z^2. Is there any way of including the hint x>0 or 'I only want positive roots of x to be used' in Solve[]? P.S. I'm not actually solving for x, it gets eliminated in the result. milstead at cs.bris.ac.uk
