WebMay 10, 2024 · Modular Math Quadratic Residues. We say that an integer x is a Quadratic Residue if there exists an a such that a2 = x mod p. If there is no such solution, then the integer is a Quadratic Non-Residue.. If a^2 = x then (-a)^2 = x.So if x is a quadratic residue in some finite field, then there are always two solutions for a.
