Look at Part 1. What factoring methods can you use?
The GCF and product-sum methods.
What is the GCF?
Factor out the GCF. What is the resulting expression?
Is the expression factored completely? How do you know?
No; you can still factor the expression inside the parentheses using the product-sum method.
Factor the expression completely. What is the result?
Look at Part 2. What methods could you use to complete the polynomial division?
Synthetic division, polynomial long division, or the reverse tabular method.
What is the result of dividing the polynomials?
What information does the remainder tell you about the dividend?
Answers vary. Students should realize that because the remainder is nonzero,
