Solution

/* b^2-4ac is known as the determinant of a quadratic equation.
The determinant tells the nature of the roots.

If determinant is greater than 0, the roots are real and different.
If determinant is equal to 0, the roots are real and equal.
If determinant is less than 0, the roots are complex and different.
