A second kind of factoring involves taking trinomials in the format:

.  These have no leading coefficient in front of the term and can basically be factored using the opposite of the shortcut that you developed in 5.1

Things you should be able to do after today:

  • factor trinomials of the type 
  • determine when a trinomial might not be factorable
  • determine possible factors when the middle term might be unknown.
