It has one real solution

Explanation:
The value b² - 4ac is known as the discriminant
This value could be one of three options:
b² - 4ac < 0 means that the quadratic equation has no real solution
b² - 4ac = 0 means that the quadratic equation has one real solution
b² - 4ac > 0 means that the quadratic equation has two real solutions

We are given that:
b² - 4ac = 0
This would mean that the quadratic equation has one real solution

Hope this helps :)
