Quadratic equation

In mathematics, a quadratic equation is a polynomial equation of the second degree. The generalized form is

Viète's formulas

Viète's formulas give a simple relation between the roots of a polynomial and its coefficients. In the case of quadratic polynomial, they take the following form:

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

: x_1 + x_2 = rac{-b}{a},

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

: x_1 x_2 = rac{c}{a}.
