Negativebplusorminus
My username is from the quadratic formula, which states that the roots of the equation 
are
![\[x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\]](http://latex.artofproblemsolving.com/d/0/1/d01fd749d6550b117a645c357f01b3c9377e5756.png)
which, when read aloud, is "negativebplusorminus..."

Pride goes before destruction, a haughty spirit before a fall.
I swear on my honor that my work and my answers are my own; if I received help, credit is given.
Equation
I derived that equation myself, and I am quite proud of it. I have a similar one for the fourth roots of 
which can be derived from inputting that equation into itself.
Notable Work

in terms of 
and 
, without trigonometry (not even using DeMoivre's theorems), and is noted for using mostly correct punctuation, capitalization, and spelling in the Art of Problem Solving classes (see AoPS Online School for how this classroom operates).

Welcome to the AoPSWiki! The AoPSWiki is a wiki (or a publicly editable online resource) project administered by the Art of Problem Solving for supporting educational content useful to avid math students. Unlike most online resources, the AoPSWiki is meant to be easily readable by even the least advanced student. Also, the AoPSWiki, being a wiki, can be edited by anyone! AoPSWiki runs on the MediaWiki software. |
Getting Started |
