  2. Warm Up Using the given function below… Find the y-intercept, the axis of symmetry, and the vertex Make a table Graph the function State whether the function has a minimum or maximum Find the value of the min/max Find the roots

  3. 4.3 Solve by Factoring

  4. Factor A factor is a number that is multiplied with another number to get a product. FACTOR FACTOR

  5. Factor A factor is a number that is multiplied with another number to get a product. Find the factors of 20: Think: which TWO numbers can be multiplied together to get a product of 20?

  6. Greatest Common Factor We’re here!

  7. Greatest Common Factor Find numbers and variables that can be factored out of every term in the expression—"factoring" means "dividing out and putting in front of the parentheses". Nothing "disappears" when you factor; things merely get rearranged.

  8. Greatest Common Factor You will use the GCF to … FACTOR equations, and SOLVE equations We will begin with FACTORING.

  9. Greatest Common Factor Factor the following equations.

  10. You Try! FACTOR the following equations.

  11. Zero Property The zero property is used to solve for . If multiple terms multiplied together equal zero, you can separate each term, set each equal to 0, and solve.

  12. Solving with GCF Solve by factoring the GCF FIRSTand then using the zero property.

  13. Solving with GCF SOLVE the following equations.

  14. You Try!!! SOLVE the following equations.

  15. Factoring when a=1 We’re here!

  16. Factoring when a=1 Factoring a trinomial is the opposite of FOIL.

  17. Factoring when a=1 1 Remember that this is where is! And when you don’t see a number, it is 1!

  18. Factoring when a=1 set up two sets of parenthesis with an in each, find two factors of c that add up to equal b, then write each factor in a parenthesis. Factoring when ,

  19. Factoring when a=1 FACTOR the following.

  20. You Try! FACTOR the following.

  21. Solving with a=1 Solve by factoring the equation FIRSTand then using the zero property.

  22. Solving when a=1 SOLVE the following.

  23. You Try! SOLVE the following.

  24. QUICK REVIEW SOLVE the following.

  25. Ticket Out The Door On a 3x5 Card answer the following. What numbers can replace the ? to make this trinomial factorable. Solve.
