Factoring Trinomials using the "Criss Cross" Method
- a critical tool for success in PC Math 11 and 12)
- note: other methods are great, but I will use this particular method in class
Factoring "Difference of Squares"
- Use this method only when...
- you have two terms in your expression (a binomial)
- each term is a perfect square
- there is subtraction between the two terms (this is called a "difference")
