Question 1130124
<font face="Times New Roman" size="+2">


I'll just go to my personal library of every Algebra book ever published and search diligently for a "Section 7.7" whose content relates to the subject of your question.  Are you new?  Please use your head for something besides a hatrack when you post questions here.  Also, use parentheses to remove ambiguity from your plain text mathematical expressions.
