Basically you plug in anything you want for a, b and c, and solve it with y = 0.

I realize that is what I need to do but the issue is I don't know how to solve it.

tyteen4a03 · Answer

It will depend on the value of a, b, c you plugged in.

anonymous · Answer

y=5x^2 + 25x +3
okay I plugged in numbers for a, b, and c

now what?

tyteen4a03 · Answer

Use the discriminant. In this case, the discriminant would be $25^2 - 4(5)(3)$.

alright now what?
