I note that people have been asking over weeks of postings for him to use grouping symbols. From my point of view, the continued absence of grouping symbols now seems willful, although I'm not really sure what his deal is.
After you've been told OFTEN to use brackets where necessary, why did you not post this as: 3x/(x-3) - 2x/(x +1) ?Psychguy98 said:3x/x-3 - 2x/x +1

the only di?erence being that the the numerator (top) and denominator (bottom) are both algebraic expressions.
