Hello Everyone,
I need help with the below question. It seemed pretty simple to me and for me the answer is "EACH statement ALONE is sufficient".
Q-> Does q have a distinct value?
1) (2q-3)^2 = q^2
2) (12-q)^1/2 = 3
My thinking behind the answer is as statement 1) gives two different roots so q does not have a distinct value. And statement 2 gives one root so q have a distinct value.
But as per the solution only statement 2 is sufficient.
Please provide your valuable feedback.

Hi rumi21,
What is the source of this question? I ask because this prompt is NOT something that you would see on the Official GMAT (and if you're using a source that is offering unrealistic material, then you would be better served working with a different resource).
The prompt should really ask: "What is the value of Q?" With this wording, Fact 1 would be insufficient (as Q could be two different values), while Fact 2 would be sufficient (as Q can be just one value).

Answer is D
since the question is asking for "Does q have a distinct value? " It is YES/NO question.
It is not asking for value of q.
1) (2q-3)^2 = q^2 leads to 1 & 3 so NO. SUFFICIENT
2) (12-q)^1/2 = 3 leads to 3 so YES. SUFFICIENT.
