Definition talk:Discriminant

I think you dropped a term. This makes the discriminant of a quadratic equation $\dfrac{b^2-4ac}{a^2}$ which clearly isn't right. --Cynic 00:08, 8 December 2008 (UTC)
It is if there ain't no $a$. Note that the polynomial this was defined on is monic. --Matt Westwood 06:17, 8 December 2008 (UTC)
