    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.

    How can I create three unique equations where the discriminant is positive, zero, or negative, and for each case, explain what this value means to the graph of y = ax2 + bx + c. ?
