Ivanshal [37]3 years ago

Answer:

The value of the discriminant is 0

Step-by-step explanation:

The discriminant of a quadratic equation is calculated as thus:

b² - 4ac and it is represented by letter D.

Hence, D = b² - 4ac..

This discriminant can take either of 3 range of values.

1. D > 0. This implies that the discriminant has a value greater than 0 and this means that the root has 2 different real solutions

2. D = 0. This implies that the discriminant equals 0 and this means that the root has only 1 solution.

3. D < 0. This implies that the discriminant is less than 0 and this means that the root has 2 different complex solutions.

Hence, D = 0 is the correct answer to this question.
