I don't think this is a good question since you can plug the number 2 in and you would get A or C as the answer.

Can someone comment their opinion on the question quality?

Mirren1 , if you choose to assign values, and your values give you two correct answers, then the fault is not in the question.

I think you might be a little confused about what happens when you pick values.

If you get two correct answers, for example, you just need to pick a different set of values to figure out which of your guesses is correct.

I picked 5. I did so because question writers are ready for you to plug in easy and ordinary numbers.

So I pick "unusual" but manageable numbers. Although it is possible to get just one correct answer at times, I almost never use 0, 1, or 2.

I wrote in my post

**Quote:**

If the algebraic equation eludes you, pick an unusual number for \(x\).

Here is a post with lots of links, all of which should help, about picking numbers and other strategies. Scroll down to @mikmcgarry if the link does not send you to his post directly:

HEREThe question is fine, and typical of a GMAT question.

Hope that helps.
