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?
