Answer 2

Answer:

The discriminant value associated with this equation is -5.

Step-by-step explanation:

The discriminant is the part of the quadratic formula under the square root.

                                              $x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

The discriminant can be positive, zero, or negative, and this determines how many solutions there are to the given quadratic equation.

• A positive discriminant indicates that the quadratic has two distinct real number solutions.
• A discriminant of zero indicates that the quadratic has a repeated real number solution.
• A negative discriminant indicates that neither of the solutions are real numbers.

If a quadratic equation has zero real number solutions, that means the discriminant is negative, so the correct value could be -5.
