How do we include math expressions (say \leq, a nonstrict inequality symbol) within a popup list?

Can we include more elaborate expressions, like \red{x=\frac{-b\pm\sqrt{b^2-4ac}}{2a} }?

Thanks.

It would be possible to implement one of the javascript-based pulldown menu approaches, which would allow arbitrary HTML within the menu items, including images or jsMath versions of mathematics. That is not for the feint of heart, however.

Your best choice may be to enter the mathematics in the "algebra" notation that students need to type in for their answers. For example, "[-b +- sqrt(b^2-2ac)]/(2a)" or something similar.
