Single polynomial equation of the second degree is termed as the quadratic equation. The discriminant of a quadratic equation provides vital information about the nature of the roots. It expresses whether the derived solution was either rational or irrational.
Find the discriminant value for the quadratic equation 10x2 + 21x - 10 = 0
Coefficient of x2 (a) = 10 Coefficient of x (b) = 21 Constant (c) = -10
Discriminant (Δ) Δ= b2 − 4 X a X c Δ = 212 − 4 X 10 X (-10) Δ = 441 + 400 Δ = 841
