What are not possible solutions of (x-5)/(x+7)+(x-2)/x=3

Nov 6th, 2014

You can't have answers to algebraic fractions that render the denominator 0 (because then you would have 1/0, which is not defined).  In this case, you have 2 solutions that would not work.  If x = 7, then the denominator of the first fraction (x-7) would equal 0.  For the second fraction, if x = 0, then the denominator (x) would equal 0.  Those are the only solutions that would not "be possible" algebraically because they're not in the domain of the function.
