  1. What's so great about factoring is that we can check our solution. If I multiply
  2. these 2 binomials together, we would do this process in reverse and end up with
  3. our original problem. If you want to get faster at factoring trinomials, you
  4. want to find the factors of 2 times 6 or 12 that add up to 13. You always want
  5. to find factors of a times c that sum to b. Finding these 2 factors allows us to
  6. rewrite the middle term. And then allows us to use factoring by grouping.
