Debato:Equaciono

I don't speak Ido, but as far as I understood this article, it sems not correct to say that a quadratic equation always has a solution. In the field of complex numbers this is the case, but for real numbers. which is the common interpretation, it is - as youo will know - not.130.89.223.240 13:12, 11 January 2006 (UTC)
