This document provides a lesson on factoring polynomials. It defines factoring as the reverse process of multiplying polynomials, where a polynomial is written as a product of simpler polynomials. It gives examples of finding the greatest common factor (GCF) of monomials and polynomials using prime factorization. It demonstrates factoring out the GCF to group like terms. Students are provided exercises to practice finding the GCF of pairs of monomials and polynomials.

LESSON 1: FACTORING POLYNOMIALS
n3 = n · n · n
n5 = n · n · n · n · n · n
n6 = n · n · n · n · n · n
n9 = n · n · n · n · n · n · n · n · n
GCF = n · n · n = n3

4𝑥
Is not a polynomial because the exponent
of the variable x in
1
4𝑥
is -1 which is not a
whole number.

4x3 = 2 · 2 · x · x · x
8x5 = 2 · 2 · 2 · 2 · x · x
GCF: 2 · 2 · x · x = 4x
