Zach Paul Factoring Powerpoint Start
Step 1 Is there a Greatest Common Factor? Yes No Example
Step 1 Continued Factor out the Greatest Common Factor. Next Step Example Last Step
Step 2 How many terms are in the polynomial? 2 3 4 or more Example Last Step
Step 3 Is the leading coefficient one? Yes No Example Last Step
Step 3 continued Find factors of third term that add up to the middle term. Next Example Last Step
Step 3 continued • Follow these steps: • Multiply the leading coefficient and the constant • Find factors of that number that add up to the middle coefficient • Rewrite the middle term using these factors • Factor by using Grouping Method Next Example Last Step
Step 3 Is there a difference of two squares? Yes No Example Last Step
Step 3 continued Use the Sum and Difference pattern to finish factoring. Next Example Last Step
Step 3 Use the Grouping Method to finish factoring the polynomial. Next Example Last Step
Congratulations You have factored the polynomial as much as possible. Restart
Greatest Common Factor Examples With a GCF: Without a GCF. Has no common factors other than 1 Has a GCF of Back to Problem
How to Factor Out a Greatest Common Factor Take the GCF and factor (divide each term by that number). Back to Problem
Examples with Different Numbers of Terms 2 Terms 3 Terms 4 Terms Back to Problem
Leading Coefficient Examples Other than 1 Leading Coefficient of 1 Back to Problem
Factoring Example Find factors of last term (15) that add up to middle term (8). (these would be 5 and 3) Back to Problem
Factoring Example • Multiply the leading coefficient and the constant (12 X 1) • Find factors of that number that add up to the middle coefficient (4 and 3) • Rewrite the middle term using these factors • Factor by using Grouping Method Back to Problem
Squares Example Perfect Square Perfect square difference Back to Problem
Sum and Difference Use the SUM and DIFFERENCE of the two squares. Back to Problem
