Find all positive integers $n$ such that $n^2 + 5n + 6$ is a perfect square. Solution Sketch: Factor the expression $(n+2)(n+3)$. Since two consecutive integers are coprime, both must be perfect squares for their product to be a square. The only consecutive squares are 0 and 1. Thus, $n+2=0$ or $n+2=1$. Checking for integers yields limited solutions. Where to Find and Download Cuban Mathematical Olympiads
