| There will always be two solutions for x. These may be real, identical or imaginary depending on the relationship between b^2 and 4ac. |
| If b^2 = 4ac, then there are two real, identical solutions. If b^2 < 4ac, then there are two imaginary solutions. If b^2 > 4ac, then there are two real, distinct solutions. |
