  1. Warm up – Solve by Taking Roots

  2. Solving by the Quadratic Formula

  3. Quadratic Formula Everything must be on the same side of the equals sign before solving

  4. Question #1Use the quadratic formula to find the zeros.

  5. Question #2Use the quadratic formula to find the zeros.

  6. Question #3Use the quadratic formula to find the zeros.

  7. Question #4Use the quadratic formula to find the zeros.

  8. The Discriminant

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

  10. Put the quadratic in standard form first!

  11.  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.

  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

  15. Homework Solving Quadratics WS Use the BEST Method
