一元二次方程的根与系数的关系,常常被称作韦达定理,这是因为该定理是16世纪最杰出的数学家韦达发现的。韦达(Vieta,1540～1603),法国人,1540年出生在法国东部的普瓦图的丰特奈一勒孔特。早年在普瓦捷学习法律,曾任巴黎裁判所的律师,后来又以律师的身份在布列塔尼地方议会里工 The relation between the root and the coefficient of a quadratic equation is often referred to as the Vedic theorem, because this theorem was discovered by Vida, the most outstanding mathematician of the 16th century. Vieta (1540–1603), a Frenchman, was born in Ventnor 1 Leconte in Poitou in eastern France in 1540. He studied law in Poitiers in the early years. He was a lawyer of the Paris Court of Justice and later worked as a lawyer in the local council of Brittany.
