Some Thoughts Too complex for me | Comment 4 of 10 |
I am aware that if the discriminant is positive there are two real solutions, if 0 there is 1 real solution, if negative there are no real solutions.

What does it mean if the discriminant is complex?  Same as negative?  1 or 2 imaginary solutions?  Can I tell whether the number of imaginary solutions is  1 or 2 based on looking at the discriminant?    Thought I would ask, instead of looking it up...
