A quadratic equation has zero real number solutions. Which could be the discriminant value associated with this equation?

• -5
• 0
• 1
• 6

If you would like to know which could be the discriminant value associated with this equation, you can find this using the following steps:

If

the discriminant of a quadratic equation is equal to zero (b^2-4ac>0), there are two real roots; and if the discriminant is negative (b^2-4ac<0), there are two complex roots.

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