Helpful Hints to Factor Simple Polynomial Expressions/Equations:

1. If possible, first factor out a greatest common factor.
2. If you have four terms, explore factoring by grouping.
3. if you have two terms, explore using the formulas for the difference of two squares, etc.
4. If you have three terms, explore to see if you have a perfect square trinomial.
5. If you have three terms, attempt trial and error.
6. If you have three terms, and you have an equation, use the quadratic formula.
7. If needed remember the useful tool of U-Substitution.
