Factoring Review

Steps to Factor Using the GCF

• Find the GCF of the numbers (use Desmos if you need).

• Find the GCF of the variables. If a variable is in EVERY term, use the one with the smallest exponent.

• Write the GCF in front of parentheses.

• Divide each term in the problem by the GCF (dividing the coefficients and subtracting the exponents), and write the remainder inside the parentheses.

• I can find the greatest common factor of the terms of a polynomial.

• I can use the structure of a polynomial to rewrite it in factored form.
