What do we know about squares?
A common key property to quickly recognize is that squares are NEVER negative. (Squares are most common, but this is also true for any other even power.)
Therefore, no matter what value x is, the inequality will always be true; \((𝑥−1)^2\) will always be greater than or equal to 0.
Since x could be anything, our answer is A, "all real numbers".

I saw this one on Focus Exam 6.
As a reminder, I recommend taking these exams twice, before doing these questions tagged "GMAT Prep (Focus)", so that your score is not inflated on these precious official practice tests.
