:After struggling through some of the math coding, I think I have clarified the article by defining the radical symbol as the principal square root only, while making it more clear that there are two square roots.

Should this page not mention that <math>x^2 -2 = 0</math> is a special case of the Fundamental theorem of algebra which states that every non-zero single-variable polynomial, (possibly with complex coefficients), has exactly as many complex roots as its degree, if repeated roots are counted up to their multiplicity?--[[User:CatWatcher|CatWatcher]] 16:59, 24 April 2007 (EDT)
