I am a 11th grade Algebra II student who is borrowing her teacher's
computer to learn things about the Internet. He has given me specific
things to do while I am on-line. One thing he wants me to do is find
out is, Who discovered the Quadratic Equation?

Thanks,
Cody

It is not known (and is unlikely to be known in the future) who
discovered the quadratic equation or who discovered how to solve the

Here are a few items related to quadratic equations:

1. The Old-Babylonians (ca. 1700 BC) stated and solved word problems
involving quadratic equations. Here's one: Length, width. I have
multiplied length and width, thus obtaining area. Then I added to
the area, the excess of the length over the width: 63. Moreover,
I have added length and width: 27. Required length, width, and
area. (Direct translation from a clay tablet. They gave a
solution as well, showing that they could solve quadratic
equations.

2. In Vedic (ancient Hindu religion) manuscripts, there are procedures
described for solving quadratic equations by geometric methods
related to actually completing a square.

Otto Neugebauer has written an interesting book on the mathematics
known by early humans.  It is called The Exact Sciences in Antiquity.
