A discriminant is a value that helps determine the nature of the solutions to a quadratic equation. In a quadratic equation of the form ax^2 + bx + c = 0, the discriminant (D) is calculated using the formula: D = b^2 - 4ac. If the discriminant is positive, the equation has two real and distinct solutions. If the discriminant is zero, the equation has one real solution. If the discriminant is negative, the equation has no real solutions.
