Comparison Question - Negative Root

GRE Quant Problem Solving
1

Given x^2 = 9

A: x

B: 3

Would a question like this appear on the GRE? The catch is that the answer is D because x could equal -3. However, the Gregmat Quant Strategy video I just watched said that they don’t test this.

But I have seen this appear in test prep material (probably from Kaplan).

Anyone know for sure? I don’t want to lose easy points.

in GRE:

if x^2 is 9 then x can be 3 or -3. ( since quadratic equations have 2 solutions )

but if x is sqrt(9) then x is only 3.
