You can use the <u>determinant</u><u> (square root)</u> of a quadratic equation to determine the number and type of solutions of the equation.
> 0 → 2 real solutions
- if is a perfect square, then rational sol'ns
- if is not a perfect square, then irrational sol'ns
= 0 → 1 real solution (double root)
< 0 → 2 imaginary(complex) solutions
