1. Hi there, did anyone here take BMO2 today? Now that it's 8:00, we can discuss the paper. What did you think?

EDIT: Sorry, we can't discuss it until 8:30. I obviously can't read.
2. Is that Edexcel? I took MD02 today, on AQA.

British Mathematical Olympiad. Nothing to do with A levels

No, the second round of the British Mathematical Olympiad. It's a bit harder than Edexcel
5. Oops sorry, lol. Never heard of it
6. Ok, so the paper is up.
7. I just answered the first two questions.But I don't know it's right or not
8. I answered the first 2, have a shaky solution of 3, and 2 pages of meaningless ramble on 4. It's better than I thought I'd do!
9. I thought it was a nicer paper than usual. But that means the boundaries will be up...
10. Well, question 1 was a much easier than normal. Although I suppose question 4 kind of made up for it. I still haven't quite got it yet. I'm all out of ideas

I answered 1 and 2 in the exam, and have since answered 3.
11. Yay, we got one. and it only took five minutes.

Something along the lines of with d=41 and c+e=7?

If we don't post again that means we can only do that one

erm. Don't know what you did but heres what I would have done;

We know that a and b must also be perfect squares. WLOG let b > a.

c has the property.

and

This results in;

Fomo factorising 2009

Therefore we obtain;

For integer solutions (a,b) = and

but the question was

not

ffs
unlucky

and is this DeanK2? why the change in user?

wlog let for an integer c.

Shoving this into equation * and squaring;

After a quick rinse.

So (a,b)

you'll find c isn't necessarily an integer

(369, 656) happens to be a solution and a contradiction to your statement...

also, if you closed your other username, why did you open a new one?

There are two more pairs.

Edit: three more pairs. Missed the trivial pair.

So we didn't even get one right ?

We got

41,1476
164,1025
369,656

What are the others?
18. ha no didnt get into this, i only got 1 mark on BMO1 !!!

19. 7= 1 + 6 = 2 + 5 = 3 + 4

Sub away and you get 4. How did you manage 8?

you have 4... the other 4 are the same, merely a is flipped with b...

you do need to show that these are the only solutions though...
