: Help me I'm lost PLEASE Thanks!!!!!!!
When using the quadratic formula to solve a quadratic equation (ax2 + bx + c = 0), the discriminant is b2 - 4ac. This discriminant can be positive, zero, or negative.
Create three unique equations where the discriminant is positive, zero, or negative. For each case, explain what this value means to the graph of y = ax2 + bx + c.

Positive Discriminant:
a=1 b=-2 c=0
(4 - 0) = 4
Has two real solutions.
Zero Discriminant:
a=2 b=-4 c=2
(16 - 16) = 0
Has one real solution.
Negative Discriminant:
a=-1 b=-2 c=-2
(4 - 8) = -4
Has two complex solutions.
