You can put this solution on YOUR website!
%28x%5E2-+1%29%2F%28x%2B1%29+=+x+-+1.
Notice that if x+%3C%3E+-1, then we can cancel terms from the left-side of the equation, to get
%28x%5E2-+1%29%2F%28x%2B1%29+=+%28%28x-1%29%28x%2B1%29%29%2F%28x%2B1%29+=+x+-+1,
which tells us that the equation is an IDENTITY as long as x+%3C%3E+-1.
Hence the solution set is the set of all real numbers except -1.
