MATHEMATICS
• Students will calculate the GCF of 2 or 3 terms of a polynomial.
• Students will apply concepts of GCFs and Factoring to write the factored form of a polynomial.
FACTORING USING GCF
Steps1. Find the greatest common
factor (GCF)2. Divide the polynomial by
the GCF. The quotient is the other factor.
3.Express the polynomial as the product of the quotient and the GCF.

Students will apply concepts of Perfect Squares and Factoring to write the factored form of the Difference of Two Squares.
DIFFERENCE OF TWO SQUARES
There must be two terms that are both squares Examples of squares
There must be a minus sign between the two terms
DIFFERENCE OF TWO SQUARES
1² = 1 11²= 1212² = 4 12² = 1443² = 9 13² = 1694² = 16 14² = 1965² = 25 15² = 2256² = 36 16² = 2567² = 49 17² = 2898² = 64 18² = 3249² = 81 19² = 36110² = 100 20² = 400

FACTORING TRINOMIALS
FACTORING A TRINOMIAL:
1. Write two sets of parenthesis, ( )( ). These will be the factors of the trinomial.
2. Think of factors of c that add up to b.
