Best ResponseYou've already chosen the best response.1but what does this tell us about the solutions?

Best ResponseYou've already chosen the best response.1youre welcome since the discrimininant is under a square root radical; it has 2 real values if it is bigger than 0; it has only 1 value if it is equal to 0; and it has only complex values if it is negative.
