  1. This first trinomial can be factored as x plus 4 times x plus 6. We want factors
  2. of positive 24 that sum to positive 10. The second trinomial can be factored
  3. into x plus 5 times x plus 4. We want factors of positive 20 that sum to
  4. positive 9. Once we have our factored form, we cancel the factors that appear in
  5. the numerator and the denominator so we're left with x plus 6. Divided by the
  6. quantity, x plus 5. Great work if you've got this as your final rational
  7. expression.
