Witryna39. (IMO Shortlist 1995, Number Theory Problem 2) Let Z denote the set of all integers. Prove that for any integers A and B, one can nd an integer C for which M 1 = {x 2 + Ax + B : x Z} and M 2 = 2x 2 + 2x +C : x Z do not intersect. 40. (IMO Shortlist 1995, Number Theory Problem 8) Let p be an odd prime. Determine positive integers x and y for ... WitrynaDiscussion. Lemma: The radical axis of two pairs of circles , and , are the same line . Furthermore, and intersect at and , and and intersect at and . Then and are concyclic. The proof of this lemma is trivial using the argument in Solution 3 and applying the converse of Power of a Point. Note that this Problem 1 is a corollary of this lemma.

A path from (0,0) to (n,n) in the xy plane is a chain of consecutive unit moves either to the right (move denoted by E) or upwards (move denoted by N), all the moves being made inside the half-plane x ≥ y. A step in a path is the occurence of two consecutive moves of the form EN.

The equation (x 1)(x 2) (x 2016) = (x 1)(x 2) (x 2016) is written on the board. One tries to erase some linear factors from both sides so that each side still has at least one factor, and the resulting equation has no real roots. Find the least number of linear factors one needs to erase to achieve this. A7.
