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

slide8

No Roots

Negative

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.

  • Parabola- the type of curve you get when you neatly graph a quadratic equation.
  • Positive, or upward, parabolas have a minimum point.

    • Negative, or downward, parabolas have a maximum point.

    • Positive, or upward, parabolas have a minimum point.
    • Negative, or downward, parabolas have a maximum point.
    • Parabolas are symmetrical along their vertical “line of symmetry” which is always halfway between points of equal height.
