## The Discriminant of a Quadratic Equation Test

The Discriminant of a Quadratic Equation Test is an online assessment that you can use to test your knowledge about this topic. The discriminant of a quadratic equation is a number that can be used to determine the nature and the number of solutions of a quadratic equation. Its value can be obtained by calculating b² – 4ac, where a, b, and c are coefficients of the quadratic equation in standard form. The discriminant can be positive, negative, or zero, depending on the values of the coefficients. If the discriminant is positive, the quadratic equation has two real and distinct solutions. If the discriminant is zero, the equation has one real solution, which is also known as a double root. If the discriminant is negative, the equation has no real solutions, but it has two complex solutions.
