Vieta's formulas ( product of quadratic polynomial roots)
In mathematics, Vieta’s formulas are formulas that relate the coefficients of a polynomial to sums and products of its roots.
P(x)=ax^2 + bx + c,
|x1||First root of second degree polynomial equation (dimensionless)|
|x2||Second root of quadratic equation (dimensionless)|
|c||Free term (coefficient of the equation) (dimensionless)|
|a||Quadratic coefficient of the equation (dimensionless)|
