Difference of Two Squares (2 parts) After completing these notes, you will be ready to do the following assignments and take the following quiz. Assignment: Quiz: WS “Factoring Special Cases” Lesson 4.4 Quiz Part 2 # 1-22 (front only) Friday March 2nd

Objective 1: After completing part 1, students should be able to recognize a difference of two squares. For a binomial to be a difference of two squares the following must be true: There must be two terms, both squares. Examples of squares are: There must be a minus sign between the two terms. Examples with a minus are:

Objective 2: After completing part 2, students should be able to factor a difference of two squares. When you are factoring a difference of two squares, use these rules: First, check to see if you can take out a GCF Second, find what multiplies by itself to make the first term and the second term. Third, fill in the signs, one should be a plus, one should be a minus. Finally, check that there is nothing left to factor within the parentheses. Sometimes you can factor another difference of two squares.

Examples :

Examples :

Examples. Make sure to take out a GCF first: Then factor the difference of two squares. Then factor the difference of two squares. Then factor the difference of two squares.

Examples. Make sure to factor completely: First, factor the difference of two squares. Then factor the difference of two squares that’s left in the parentheses. Stays the same. Factors again.
