Talk:Quadratic equation

Can someone please fix the line:

"move b/2a"

so that it is in math formula? For some reason i can;t make it work. emma 10:33, 9 January 2007 (UTC)

${\frac {b}{2a}}$ <-- Like that? -- Creol(talk) 10:46, 9 January 2007 (UTC)

do'h! thankyou. Storeye 11:02, 9 January 2007 (UTC)

Quadratic function or quadratic equation?

Which one is it? TeleComNasSprVen (talk) 07:56, 2 June 2010 (UTC)

Is this article too simple?

Okay, I know that this is “Simple English Wikipedia,” but I think we can all agree that simple is not the same thing as wrong. The very first sentence states that “A quadratic equation is an equation in the form of $ax^{2}+bx+c$,” but $ax^{2}+bx+c$ is not an equation, it’s an expression. (An equation is a statement that two expressions are equal.) Candidates for a better way to phrase the opening sentence might include:

1. A quadratic equation is an equation of the form $ax^{2}+bx+c=0$, where a is not equal to zero.
2. A quadratic equation is an equation that can be written in the form $ax^{2}+bx+c=0$, where a is not equal to zero.

I know I might make some people mad but I really feel this can be said in a simple way. It may even be possible to explain why a is not zero in the case of the quadratic equation and why it cannot be zero in the case of the quadratic formula. — Preceding unsigned comment added by Ciggol (talk • contribs)

Well, if you can find out an idea to make it simple, understandable, and right, by all means go ahead. :) I on my behalf can't exactly understand what you've just explained up here ^, but I don't see any wrong in your changing it in the right way you think it should be. If it's wrong, you can always undo it. Belle ^{tête-à-tête} 01:02, 17 September 2010 (UTC)

Well, I just made the change I suggested in first list element, but in retrospect maybe I should have just left things the way they were. Now it is an equation, a quadratic equation, but the sentence is still not exactly correct and it may be unnecessarily confusing. Unless there are any objections I think I will leave it the way it is for now, but I would not be offended if/when someone wants to change it back :)
