Question

What are the possible outcomes when using the quadratic formula?

Answer 1

The discriminant of the quadratic formula tells you about the nature of roots the equation has.

Explanation:

`b^2−4ac=0`, one real solution
`b^2−4ac>0`, two real solutions
`b^2−4ac<0`, two imaginary solutions

If discriminant is a perfect square, the roots are rational or else if it is not a perfect square, the roots are irrational.
