  2. Skills Check – Solve by Taking Roots

  3. Questions over HW?

  4. The Discriminant

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

  6. Put the quadratic in standard form first!

  7.  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.

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

  9. Discriminant 2 real Roots ZerO Negative

  10. Discriminant One real Root Positive Negative

  11. Discriminant 2 imaginary Roots Positive ZerO

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

  13. Determine the number & type of roots.Example: 2 1 Real Root

  14. Determine the number & type of roots.Example: 3 2 Real Roots
