Question 154444: "why did quadratic equation called quadratic equation"
Answer by scott8148(6628)   (Show Source):
You can put this solution on YOUR website! "To the best of our knowledge the origin of the term "quadratic" is Latin. It is derived from quadratus which is the past participle of quadrare which means "to make square." From this it is clear that part of the word is connected to the Latin word for "four," though not a way which one might expect: it refers to squaring, and a square is a regular four-sided figure."
apparently, the method of "completing the square" was first used by the Babylonians about 1700BC
