Grouping
Try these 2 on your own. Which "group" can you factor out?
1. 3x3(x ‐ 6) + 4(x ‐ 6)
2. 9y(w2 + 1) ‐ 4x(w2 + 1)
Students can factor algebraic expressions using the grouping method.

Grouping directions
Factor by Grouping:1. There should be 4 terms.2. Break quadranomial into 2 groups.3. Factor each group by GCF.4. Bring out the factor that "matches."5. The other factor is made up of the left over 2 terms.
Students can factor algebraic expressions using the grouping method.

Metacognitive Skills Survey:
Unit 2- Polynomials
Metacognitive skills refer to the ability to judge how well you have learned something and to effectively direct your own learning and studying. This is a self-evaluation tool designed to help you focus your studying and to improve your metacognitive skills with regard to Intermediate Algebra HVCC.
Use the scale below to assign a number to each topic:
1 = I know I don’t understand how to do these problems.
2 = I understand how to do the problems in this category, yet make a few mistakes.
3 = I am confident I can do any problems in this category correctly.
Topic or Skill
Pre- Unit
Mid- Unit
Post- Unit
