Code Standard standard:
Use the structure of an expression to identify ways to rewrite it. Focus on numerical expressions, such as recognizing 532 - 472 as a difference of squares and see an opportunity to rewrite it in the form (53+47)(53-47). Focus on polynomial expressions in one variable, such as seeing an opportunity to rewrite a2 + 9a + 14 as (a+7)(a+2).
