When you say you can do this in wordpress you must be referring to wordpress.com site since to use it in wordpress (my installation at least) I needed to install a plugin. Dave Thanks for the link to your article,

I also observed that you are having a hard time writing equations. You can actully write complex equations in wordpress like $latex x =\frac{-b \pm \sqrt{b^2-4ac}}{2a}$. That is called Latex coding. I have a tutorial here: http://math4allages.wordpress.com/2009/12/06/latex-tutorial/ I have created an extensive article about quadratic formula here:

When the quadratic equation is written as x^2+D1*x+D0=0, where D1=b/a and D0=c/a, is there analytic formula for the equal roots in expression of both D1 and D0 but it still be equal to -D1/2 or -b/2a.

For example for creating abcde formula of the following polynomial ax^4 + bx^3 + cx^2 + dx + e = 0 I think we need to develop a new procedure of creating the quadratic formula that can be applied to create analytical roots of higher polynomials. For example for creating abcde formula of the following polynomial

ax^4 + bx^3 + cx^2 + dx + e = 0
