I came across this today and could not quite figure it out. The statement in question is, to paraphrase: Since the squared expression is always going to be positive it can be excluded from the sign diagram because it will have no effect on the sign of the quotient. Here is the text:
It seems to me that the squared term's positive sign has a lot to do with the sign of the quotient. I mean, if the term is the only term in the numerator then the denominator has to be positive to get a positive quotient and it has to be negative to get a negative quotient. So...what is the author talking about here?
