False

Since you cannot take the square root of a negative number anyway, it does not make sense to include solutions that yield a negative value under the radical. Thus, while values that make the radicand negative are often not seen in the answer, they are ignored anyway, meaning that solving the radical in this way will give all of the possible answers.
