how can I tell if a discriminate solution is two complex solution, one real solution, or two real solution?
b² -4ac is the discriminant
If b² -4ac > 0 then there are two real solutions.
If b² -4ac = 0 then there is one real solutions.
If b² -4ac < 0 then there are two imaginary/complex solutions.
(Technically, complex numbers include all real numbers as well as all imaginary numbers.)
