Question

What is true about the solutions of a quadratic equation when the radicand of the quadratic formula is zero?

Answer 1

If the radicand is zero, you will have two identical, rational solutions

Answer 2

@blurbendy -two identical, rational solutions? So does that mean there is really only one solution?

Answer 3

I would say there is only one solution, -b/2a

Answer 4

i believe you would have a multiplicity. so if you had (x-2)^2, that would be a multiplicity of 2.

Answer 5

which means u really have only one solution, right? x=2

Answer 6

good question! i'm not entirely positive.

Answer 7

yeah, there is only one solution:
b^2 - 4ac > 0: two real solutions
b^2 - 4ac = 0: one real solution
b^2 - 4ac < 0: no real solutions
