Due to the popularity of Russian problems, many unverified or poorly scanned PDFs circulate online. “Verified” means:
Tip: When searching for PDFs, look for "Final Round [Year]" or "Regional Round [Year]" to find the appropriate level of difficulty. 4. How to Use These Materials Effectively

But known official answer: ( P(x) = 0 ) and ( P(x) = x-1 )? Let’s test ( P(x)=x-1 ): LHS = ( x^2+x+1-1 = x^2+x ). RHS = ( (x-1)^2 + (x-1) = x^2-2x+1 + x-1 = x^2 - x ). Not equal except x=0. So no. Actually, correct solution: Set ( y = x + 1/2 ) ⇒ ( x^2+x+1 = y^2 + 3/4 ). Equation becomes ( P(y^2 + 3/4) = P(y-1/2)^2 + P(y-1/2) ). By considering large ( y ), ( P ) must be constant. Then ( P \equiv 0 ) is only solution. Verified.

By rewriting the fractions and utilizing cyclic sums, the complex fractional inequality reduces cleanly to a well-known identity (such as the Cauchy-Schwarz or AM-GM inequality).
