  1. Warm-Up: January 5/6, 2012 • Factor each of the following expressions:

  2. Homework Questions?

  3. Today’s Agenda • Finish Section 6-2 Notes (Example 4, You-Try #4) • Review Chapter 5 Test • Section 6-3 Notes • Homework Time (time permitting)

  4. Solving Quadratic Equations by Factoring Section 6-3

  5. Zero Product Property • For any real numbers a and b, if ab=0, then either a=0, b=0, or a and b both equal zero.

  6. Example 1 – Solve by Factoring

  7. You-Try #1 – Solve by Factoring

  8. Writing Quadratic Equations • Given roots p and q, the quadratic equation must be equivalent to (x-p)(x-q)=0

  9. Example 4 • Write a quadratic equation with -2/3 and 6 as its roots. Write the equation in the form where a, b, and c are integers.

  10. You-Try #4 • Write a quadratic equation with 3/4 and -2 as its roots. Write the equation in the form where a, b, and c are integers.
