Let ( t = x^2 + x + 1 \ge \frac34 ). Then ( Q(t) = Q(x)^2 ). Iterating: For ( x_0 \in \mathbbR ), define ( x_n+1 = x_n^2 + x_n + 1 ). Then ( Q(x_n+1) = Q(x_n)^2 ). If ( |Q(x_0)| > 1 ), then ( |Q(x_n)| ) grows without bound as ( n\to\infty ), but ( x_n ) is bounded only if ( x_0 ) is in some finite range — actually ( x_n \to \infty ) for ( x_0 \ge 0 ) or ( x_0 \le -2 ) maybe. Standard solution: Only constant solutions work. Check ( Q \equiv 0 ) ⇒ ( P \equiv -1/2 ). Check ( Q \equiv 1 ) ⇒ ( P \equiv 1/2 ). Check ( Q(x) = x^m ) impossible because degree doesn’t match. Also ( Q(x) = 0 ) or 1 for all ( x ) in the set of iterates forces ( Q ) constant. So ( P(x) = c ) with ( c^2 + c = c ) ⇒ ( c=0 ) or ( c=-1/2 ) from original eq? Wait, original: ( P(t) = P(x)^2 + P(x) ) constant ⇒ ( c = c^2 + c ) ⇒ ( c^2 = 0 ) ⇒ ( c=0 ). So only ( P\equiv 0 ) works? But check: ( P\equiv 0 ) ⇒ ( 0 = 0+0 ) OK. ( P\equiv -1/2 ) ⇒ ( -1/2 = (1/4) + (-1/2) = -1/4 ) — false. So only ( P\equiv 0 ).

Finding accurate, well-translated, and verified solutions can be challenging since the original problems are written in Russian. However, several highly reputable sources provide verified PDFs and archived materials:

School Stage: The initial round open to all students.Municipal Stage: Held for winners of the school round.Regional Stage: A significant step up in difficulty, filtering the best talent from various Russian oblasts.Final Stage (All-Russian): The culminating event where the top students in the country compete over two days.

The initial stage, open to all students, focusing on creative problem-solving.

: Problems rarely rely on standard algorithms; they require novel insights.

Number theory in these competitions goes far beyond basic divisibility rules. Expect to master:

I’ve included for five classic, non‑trivial problems. For a complete PDF, I will also give you a trusted source link at the end.

To save you time, here are three specific, verified PDFs that are known to be accurate within the mathematical community. Iterating: For ( x_0 \in \mathbbR ), define

If you are downloading a PDF for the Final Stage (All-Russian), expect to see heavy representation in these areas:

When you open a PDF, cover the solution section completely. Spend at least 1 to 2 hours attacking a single problem using different strategies before even glancing at the hint or answer. Maintain a Error Log

is divisible by 3. If neither is a multiple of 3, their squares a2a squared b2b squared both leave a remainder of 1 modulo 3. Therefore,

Instead of doing an entire test from start to finish, isolate sections of your PDFs. Spend a week focusing exclusively on Russian Geometry problems, then switch to Russian Number Theory. This helps you notice patterns in how Russian examiners construct problems. To help us narrow down your study plan, let me know:
