> Do u need to apply quad eq??

That question is discussed in detail here: which-of-the-following-is-always-equal-to-sqrt-9-x-2-6x-54341.html



Which of the following options always equates to \sqrt{9 + x^2 - 6x} ?

A. x - 3
B. 3 + x
C. |3 - x|
D. |3 + x|
E. 3 - x


\sqrt{9 + x^2 - 6x} =

=\sqrt{(3 - x)^2} =

=|3 - x|

Note that both |x - 3| and |3 - x| represent the distance between x and 3. Hence, it follows that |x - 3| = |3 - x| .


Answer: C
Yup I got this but thank you for posting it again , it will surely help others who might have made silly errors like me 🫣😅

Glad there is no pure algebra , it’s been over 7-8 years since i last encountered all of that 😅
Reminded me of ring theory and linear algebra

Thank you for your prompt response
I high appreciate it 🙏🏻

Again, to make it as clear as possible: pure algebraic questions are no longer part of the Data Sufficiency (DS) syllabus. However, they are still very much a part of the Problem Solving (PS) syllabus.

I got this question in Q sectional mock, it was easy duh I made a silly error and it was really bothering me lol , which again makes me wanna question the sectional quants mocks on gmat forum quiz/ test section !!!! are they updated or we can still encounter questions which are not part of GMAT anymore ??

DS quiz should not contain questions not relevant to GMAT Focus. If you encounter one, please share. Thank you!
Hi Bunuel,

When you said "DS quiz should not contain questions not relevant to GMAT Focus" in the reply above, are we talking about Forum Quiz or GMAT Club Test?

Sorry if this is a stupid question. I got confused when the previous question talked about "sectional mocks" and forum quiz at the same time, which to me are actually two different products?

Would greatly appreciate your advice.

Neither GMAT Club Quizz nor GMAT Club tests contain irrelevant question.

In GMAT Club Quiz, we offer more detailed difficulty filters. However, in GMAT Club Tests (which you're referring to), we've always had only three levels: Easy, Medium, and Hard.

Critical Reasoning Butler: May 2025
May 20CR 1CR 2

_________________________________
CR 1

The restrictions on what one can carry inside an airplane are surely too severe. Airlines these days issue a long checklist of items that cannot be carried inside an aircraft making it cumbersome for the travelers to keep a track of all these items. In any case, barely two percent of travelers are ever caught with these restricted items, so it’s best if these restrictions are removed.

Which of the following is an assumption on which the argument depends?

(A) The restrictions themselves do not discourage people from carrying restricted items on to airplanes.

(B) The restrictions have been implemented all across the world.

(C) There is no scope for corrupt practices on the part of those enforcing these restrictions.

(D) There have been instances when an innocent traveler has been wrongly detained by over cautious airline personnel.

(E) Criminals are hardly likely to carry restricted items with them on an airline.

__________________________________
CR 2

When unemployment rates are high, people with full-time jobs tend to take fewer and shorter vacations. When unemployment rates are low, people tend to vacation more often and go away for longer periods of time. Thus, it can be concluded that full-time workers’ perceptions of their own job security influence the frequency and duration of their vacations.

The argument above assumes that

(A) the people who take the longest vacations when unemployment rates are low have no fear of losing their jobs

(B) travel costs are lower during times of low unemployment

(C) most people prefer to work full-time jobs

(D) workers’ perceptions of their own job security are in some way related to the unemployment rate

(E) workers’ fears of losing their jobs have increased recently
