Efficiency in Industrial Design Modeling

An industrial designer is using the trinomial 18n237n+1518n^2 - 37n + 15 to model the load distribution of a new shelving unit. When factoring this expression using the trial and error method, the designer uses the 'GCF elimination shortcut' to reduce the number of potential trials. State the rule of this shortcut and provide one example of an invalid trial binomial (using factors of 18n218n^2 and 1515) that can be rejected because it violates this rule.
