Click on this link to the site on “How to factor second degree polynomials (quadratic equations)” to learn how to factor second degree equations with different methods. Then answer:

- a) Fill in the gap:

*We start by ordering the terms in our equation from highest to lowest power, to put the equation in ____________ format.*

- b) If it is a simple polynomial and we have a lot of practice, what method could we use?
- c) With what method we identify all possible factors of the “a” and “c” terms?
- d) The “Triple Play” method is similar to what other method?
- e) When do we use the “Difference of Two Squares” as method to factor second degree polynomials?
- f) When do we use the “Quadratic Formula” as method to factor second degree polynomials?
