Does gmat test the concept of real and imaginary roots from quadratic equations?

I have not seen any questions regarding the graphs and roots

isnt it C?

I think its C

my bad its E

wizako has many questions regarding that

you can register and take free tests over there

but i think they only give you 650 plus questions to solve

moreover they had given questions regarding parabolic nature of quadratic equations which could be solved by only using graphs

I try to focus only on official questions

bb do we get such type of questions?

No, you will not run into questions like these.

GMAT is deemphasizing calculation-heavy questions but they do have some functions things. I would say you have a 0.01% chance of hitting smth like that on the GMAT.

Interesting enough, we do have Bunuel posting that question back in 2016: y-x-2-bx-256-cuts-the-x-axis-at-h-0-and-k-0-if-h-and-k-ar-214646.html and it is marked as 800+ (meaning too hard really for the real GMAT question) but Bunuel felt it was within the GMAT constraints.

But does not look like it requires a chart or a graph. The question is Very Hard based on the timer statistics. I would say you are much better served making sure you get high accuracy on the medium and hard questions rather than VERY Hard. It is not a bad question however. It is within the GMAT-testing parameters.

Usually GMAT uses this approach to difficulty: Instead of giving you a lot of calculations, they give you a situation you have never seen or a question you have never solved before. That requires thinking and applying skills you know to a situation you are not familiar with. This question is kind of like that - it forces you to apply a solution to a situation you never deal with. However, the calculation load is a bit too high and it assumes that you know how to graph that equation and know how that form of equation looks like. GMAT would not do that. You are not expected to recognize the shape of a graph with just an equation and GMAT would tell you if that’s an equation of a circle for example or something else. That’s not the part that is tested. What they test is your ability to apply what you know to a situation that you don’t know. In other words, this is too hard for a real question and I would not worry about meeting it on your test day. If you do, I will send you $275 for your gmat retake

In order to complete a reading assignment on time, Terry planned to read 90 pages per day. However, she read only 75 pages per day at first, leaving 690 pages to be read during the last 6 days before the assignment was to be completed. How many days in all did Terry have to complete the assignment on time?

Can u explain this ques bb

I like poking at questions but this one actually has quite a few expert explanations: in-order-to-complete-a-reading-assignment-on-time-terry-planned-to-re-140555.html

Often/usually, there are multiple ways to solve questions on the GMAT. Brute force that some people prefer - just solve it with an equation or you can solve it more elegantly using picking numbers, backsolving, etc. I like this solution for example:

by psychedelictwirl

Her original goal was to read 90pages per day.
Thus in 6 days she would have read 90*6= 540 pages.
Since she was left with 690 pages means she was 150pages short of target.
Since the difference between 90 pages and 75 pages is 15 pages.
The number of days would be 150/15 = 10 days
Total number of days to complete assignment 10 + 6 days = 16days.

This is also good:

Well, How about plugging in.

Start off with C=25 days.
We know that for 6 days its 690 pgs. So 25-6=19 days left
Now we have to multiply 75 and 19=1425
Now add 1425 and 690= 2115 pgs
But the planned rate is 90 pgs. Multi ply 90 and 25 we get 2250 pgs.
This is more than 2115. So we need to plugin a lesser number.
Plugin ans choice b and get the answer.

but a little too convoluted

If 1/y= 7/2 then 1/y+2=?
