Best ResponseYou've already chosen the best response.0The Discriminant: The expression in the square root, D = b^2  4ac , is called the discriminant, because its value can be used to discriminate between the different types of solutions that are possible: D > 0 results in two real solutions: If D is a perfect square (like 4, 9 64, 100, etc.) then you get two rational solutions. If D is a not perfect square then you get two irrational solutions.

Best ResponseYou've already chosen the best response.0the discriminant value of ax^2+bx+c=0 always D=b^24ac for this case, x^25x4=0 it means, a=1, b=5, c=4 can u determine the value of disciminant (D) = ... it is a start
