- Given the discussion this question has generated, I would suggest to
- the original poster that he write to ETS and complain that the
- question is poorly worded. GRE questions should not designed to be
- tricky, ie., to depend upon knowing that the positive root was
- intended. I certainly don't remember having it impressed upon me that
- the surd always implies the positive square root. In fact, I remember
- equations being solved by taking *the* square root of both sides.
- There were invariably a positive solution and a negative solution.
