Discriminant - Formula, Rules, Discriminant of Quadratic …
The discriminant in math is defined for polynomials and it is a function of coefficients of polynomials. The discriminant of quadratic equation ax^2+bx+c = 0 is b^2 - 4ac and it is denoted by D or Δ.
Discriminant - Wikipedia
In mathematics, the discriminant of a polynomial is a quantity that depends on the coefficients and allows deducing some properties of the roots without computing them. More precisely, it is a polynomial function of the coefficients of the original polynomial.
