How do people fail to answer even ONE question on a BMO1 paper?

Scroll to see replies

If the questions in that paper had been posed more recently, it would be classified as an easy paper, excluding this years paper of course (as that was pitiful).

Though that may be largely due to the level preparation done by BMO candidates these days compared to a decade ago.

Probably have to look at the multiples and different cases as such.

Basically if we prove they cant share a common factor then i think we are done.

Cracked it. Got a nice re written neat solution.

Ignore the let k= bit and k>=5 bit. The square is the key part then the next square after m(m+1)+1 and square before that.
You could go from the perfect squre part and prove that there are no solutions for m(m+1)+1=k^2 but thats long and not needed.
