1 USAJMO 2023 1. Find all triples of positive integers (x,y,z) that satisfy the equation 2(x+ y + z + 2xyz)2 = (2xy + 2yz + 2zx+ 1)2 + 2023. 2. In an acute triangle ABC, let M be the midpoint of BC. Let P be the foot of the perpendicular from C to AM. Suppose that the circumcircle of triangle ABP intersects line BC at two distinct points B

Note: This shouldn't work since we see that m = 12 is a solution. Let the initials for both series by 1, then let the ratio be 7 and the common difference to be 6. We see multiplying by 7 mod 12 that the geometric sequence is alternating from 1 to 7 to 1 to 7 and so on, which is the same as adding 6. Therefore, this solution is wrong.

Solution 3 (Less technical bary) We are going to use barycentric coordinates on . Let , , , and , , . We have and so and .

Connect segment PO, and name the interaction of PO and the circle as point M. Since PB and PD are tangent to the circle, it's easy to see that M is the midpoint of arc BD. ∠ BOA = 1/2 arc AB + 1/2 arc CE. Since AC // DE, arc AD = arc CE, thus, ∠ BOA = 1/2 arc AB + 1/2 arc AD = 1/2 arc BD = arc BM = ∠ BOM.
