In summary, we discussed various mathematical problems including sequences, polynomials, integrals, and functions. We also explored combinatorics, probabilities, calculus, and linear algebra. These problems were submitted by referees who will post solutions on the 15th of the following month. The rules for solving problems were also outlined, including the use of proofs and resources.

What do you mean by quadrature? I can find several potential meanings that could be relevant. For example, it could mean doing an integral. It could mean a particular method of numerical solution. It could mean something about fitting things to a rectangle. It could mean something about a quadratic equation.
This problem was contributed by @wrobel so we have to ask him. I guess it only refers to the quadratic form of the equation. The clue is to use the symmetry.
