Origin of the Quadratic Equation
Date: 7/12/96 at 10:52:39 From: john terrell Subject: Quadratic Equation Origin 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

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. -Doctor Jerry, The Math Forum Check out our web site! http://mathforum.org/dr.math/
