In algebra, the discriminant gives information about the nature of its roots. typically denoted by Greek letter Delat(Δ) or a capital 'D'.
To quadratic equation , the discriminant of the quadratic polynomial: ax^2+bx+c, is Δ = b^2-4ac.
The information of the discrimainat is if Δ > 0, the polynomial has two real roots, if Δ = 0, the polynomial has one real double root, and if Δ < 0, the polynomial has no real roots.
