  1. Since we've already factored the 3 x out, we want to work with this trinomial.
  2. This top number should be a times c. A is the coefficient in front of x squared
  3. and c is our constant term. So 12 times negative 2 equals negative 24, this
  4. choice. The bottom number is the b or the coefficient in front of x, so negative
  5. 5. Great work if you found these two numbers. I know this question was tricky,
  6. since I threw another polynomial at you. But, we want to make sure we work with
  7. factoring this quadratic.
