Calculate the discriminant and use it to determine how many real-number roots the
equation has.
3x^2 - 6x + 3 = 0
three real-number roots
two real-number roots
one real-number root
no real-number roots
without drawing the graph of the equation, determine how many points the parabola has in common with the x-axis and whether its vertex lies above, on, or below the x-axis.
y = 2x2 + x - 3
1 point in common; vertex on x-axis
2 points in common; vertex below x-axis
2 points in common; vertex above x-axis
no points in common; vertex below x-axis
