You can use the what of a quadratic equation to determine the number and type of solutions of the equation?

You can use the determinant (square root) of a quadratic equation to determine the number and type of solutions of the equation.

> 0    → 2 real solutions

= 0    → 1 real solution (double root)

< 0    → 2 imaginary(complex) solutions
