**General Guidelines for Factoring **(Read Mod. VIII page 12)

- Is there a common factor? If so, factor it out
**FIRST!**This will always make the remaining problem easier and sometimes it will not be possible to factor until this has been done. - How many terms are there?

**2 terms:**Is it a Difference of Squares, a Difference of Cubes, or a Sum of Cubes.

**3 terms:** Factor by trial and error or use the **AC method**.

**4 terms:** Use factoring by grouping

3. Make sure that you have factored completely!
