Ex: If you see 72, try 8 - 9 first (followed by 6-12,4-18,4-24,2-36, and 1 - 72 in that order). 3) The GCF of each binomial factor must be one! Therefore, don't even consider a factor like: (Sac + 12) becasue you could factor out 4. 4) Test your potential answer from part 3 by multipling the inner and outer terms. If you cannot use these results to make bz, go back to step 2. If you can make bz, put in the signs. The following problems were selected to teach the importance of rule number 2: try numbers closest together first. You should get the correct answer on your first trial 50% of the time; on the second trial 97% of the time.
