Question 180084: I have a question about discriminant and quadratic equations. Can anyone answer the below question?

"You have a good description of the discriminant, explaining that it does come from the quadratic formula. Why do you think it works? By this I mean for example, why when it is greater than 0, will you have two real number solutions"?

Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
Because the quadratic formula says
x =[-b/(2a)]+[sqrt(discrim)/(2a)] or x= [-b/(2a)]+[sqrt (discrim)/(2a)]
If that discrim is not zero you are bound to end up with two possible
value for x.
