What is a Discriminant?
A discriminant is a value that determines the nature of the solutions of a quadratic equation. It is calculated using the coefficients of the quadratic equation and helps to identify whether the equation has real or complex solutions. The discriminant is denoted by the symbol “D” and is calculated using the formula:
D = b^2 – 4ac
Where a, b, and c are the coefficients of the quadratic equation.
What is a Discriminant Calculator Website?
