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.

$\sqrt{b^{2}-4ac}$ > 0 → 2 real solutions

if $\sqrt{b^{2}-4ac}$ is a perfect square, then rational sol'ns

if $\sqrt{b^{2}-4ac}$ is not a perfect square, then irrational sol'ns

$\sqrt{b^{2}-4ac}$ = 0 → 1 real solution (double root)

$\sqrt{b^{2}-4ac}$ < 0 → 2 imaginary(complex) solutions
