where \(D_{R1}\) and \(D_{R2}\) are the 2 Square Roots of the Discriminant \(D\) calculated as
\(D=B^2-4AC\) ...(3)
Since the 2 Square Roots of the Discriminant only differ in sign (i.e. One Square Root is Negative of the Other), the 2 Square Roots of the Discriminant can be specified by a common variable \(D_{R}\) and
accordingly, the formula for calculation of Roots/Solutions of Quadratic Equation is given as
