With regards to quadratic equation comment, Aside from being one of the simplest non trivial derivations/ uses of algebra you could teach children (and often the derivation is not taught...), the solutions to polynomials have a very important place in the history of mathematics and the development of modern algebra (which of course is also not taught...) Should children all be forced to gain an appreciation for the significance and origins of modern algebra? I think, yes. We force them to learn history of whatever country they reside in, year after year. We force them to learn and appreciate novels and literary analysis (equally "useless"). If they don't have an appreciation for mathematics is or does (and quadratic equation is a simple example leading up to some VERY important developments), how will they really know whether or not they want to have a career involving math some way in the future?
