What is the quadratic formula used to solve ax^2 + bx + c = 0?

x = (-b ± √(b² - 4ac)) / (2a)x = (-b ± √(4ac - b²)) / (2a)x = (b ± √(b² + 4ac)) / (2a)x = (-b ± 4ac) / (2a)

What does the discriminant (b² - 4ac) indicate in a quadratic equation?

The maximum value of the functionThe number of real solutions to the equationThe vertex of the parabolaThe axis of symmetry

If a quadratic equation has a discriminant of 0, what can be concluded?

There are two different real solutions.There is one real solution that is a repeated root.There are no real solutions.The solutions are complex and distinct.
