👉 A quadricentric number is a number that can be expressed in the form of $a + b\sqrt{c}$, where $a$, $b$, and $c$ are integers. This means that it is a real number whose square root expression involves only the square roots of integers. The term "quadricentric" comes from the Latin word for "square," which is derived from the Greek words "quadratus" (square) and "centenus" (number).
