okay, basic stuff:
ax^2 + bx + c = 0 and the discriminant is b^2 - 4ac.

Okay so far? Kewl

I need to "play" with these numbers and come up with a positive, zero and a negative. Then, graph the corresponding equation and give examples of how they are used in the real world.

I am thinking a spring as in a shock absorber for a car for a negative?

no idea for any of the others....

Can you point me in the right direction? Please.

(you don't have to do the math, just give me an idea for real every day uses. Or where I can find these examples. It is my homework and I would like to do it on my own, just completely lost here, so looking for a little help)
