Answer 2

The correct answer is:

Discriminant.

Step-by-step explanation:

The definition of the word "discriminant," regardless of mathematics, is "an agent or characteristic that enables things, people, or classes to be distinguished from one another. "

In mathematics, this is true of the discriminant of a quadratic equation. The discriminant tells us how many solutions a quadratic equation will have. This is because we cannot have a real number square root of a negative, the square root of 0 is 0, and the square root of any positive real number will yield two results. Thus the expression under the square root, b²-4ac, is the discriminant.
