Whenever I'm faced with an inequality like this one:
1+x/1-x > 0
I don't really use a set plan. I basically just take the numerator and denominator and solve for them separately. Example:
1+x>0 ----> x>-1
1-x>0 -----> x<1
Is it OK to do this for all inequalites with numerators and denominators that are just set against 0 as opposed to a quantity, or am I missing something? Thanks.
