Discriminant- the value inside the radical ( ) when you do the quadratic formula. This value can be positive, zero, or negative. Roots of a Polynomial- the answer(s) for x. Where the graph of the parabola intersects the x-axis. There can be two roots, one root, or No roots.
Two Roots Positive
One Root Zero
No Roots Negative

Where the graph of the parabola intersects the x-axis. There can be two roots, one root, or No roots. • Parabola- the type of curve you get when you neatly graph a quadratic equation. • Positive, or upward, parabolas have a minimum point.
When the a in, ax2, is Positive Upward Happy Minimum
