Chapter 8­1 Monomials and Factoring
A monomial is in factored form when it is expressed as the product of prime numbers and variables, and no variable has an exponent greater than 1.
Factor ­20x3y2 completely:

Greatest Common Factor of Monomials: greatest number that is a factor of both monomials
Factor each monomial and then find the common factors and multiply them together.

Factoring polynomials: reverse of multiplying.
Technique #1 to factor:
Factoring by Grouping:
4qr + 8r + 3q + 6

Zero Product Property:
If the product of two factors is 0, then at least one of the factors must be 0.
For any real numbers a and b, if ab = 0, then a = 0, b = 0, or both a and b equal zero.
