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

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

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

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

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

good question! i'm not entirely positive.

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
