In the Quadratic Formula, what does it mean if $b^2-4ac>0$, $b^2-4ac<0$, and $b^2-4ac=0$? Concerning the Quadratic Formula:
What does it mean if  $b^2-4ac>0$, $b^2-4ac<0$, and $b^2-4ac=0$?

If $ b^2 - 4ac > 0 $ then you will get 2 real roots of the quadratic equation.
If $ b^2 - 4ac < 0  $ then your under root part will become negative and so the equation will have 2 complex roots.
If $ b^2 - 4ac = 0 $ then you will have one solution which will be $ -b/a $
this might help you understand better
