Two sets of values are very common for such situations. Recall that when we simplify surds of the form (a + ./b)^2 and (a - ./b)^2, we get different signages for the surviving surd, but the sifnages are the same for the non-surd.
As such, two sets of answers, which obviously have to be symmetrical (as is the case in your workings), should be obtained.

Noted thank you!! I wasn't sure as the question didn't specify if there were to be multiple values.
