`
Every quadratic equation
has either
1. Two real solutions
2. One real solution
3. Two conjugate imaginary solutions
The quadratic equation:
has two real solutions when the " ± " part gives two different
answers, one for the + and another for the -. This will always
be the case when the radicand, or "discriminant",
 ¹0
If
> 0, the two solutions are real, and when
< 0, the two solutions are conjugate imaginary
numbers.
However, if
= 0, there is but one real solution, because the
"±" part is "±0", and whether we add 0 or subtract 0, we still
get the same number.

You can put this solution on YOUR website! In quadratic equations, what matters is the value of discriminant  . If it is positive, there are 2 solutions. You can't get a root from negative discriminants. In that case there is no solution. If the discriminant is zero, there is one solution.
