  2. Questions over HW?

  3. The Discriminant

  4. The Discriminant tells how many & what type of solutions the quadratic has.

  5. Put the quadratic in standard form first!

  6.  If the discriminant is POSITIVE, then you will have 2 real roots.  If the discriminant is ZERO, then you will have 1 real root.  If the discriminant is NEGATIVE, then you will have 2 imaginary roots.

  7. Discriminant Foldable Notes Fold your paper over (top to bottom leaving about an inch at the bottom). Positive ZerO Negative

  8. Discriminant 2 real Roots ZerO Negative

  9. Discriminant One real Root Positive Negative

  10. Discriminant 2 imaginary Roots Positive ZerO

  11. Determine the number & types of roots.Example: 1 2 Imaginary Roots
