Documenting Standard Procedures for Area Factoring

As a technical writer for a manufacturing plant, you are drafting a training manual on how to determine the lengths of custom rectangular parts from their area models. The standard example used in the manual is the area expression 18x237xy+15y2{}18x^2 - 37xy + 15y^2. From memory of the trial-and-error factoring procedure, list the specific factor pairs for the leading term and the last term (remembering to apply the correct signs), and state the final binomial pair that correctly produces the middle term of 37xy-37xy. Describe these recalled facts clearly so they can be transcribed into the manual.
