论文摘要
本说明的目的是指出[M. Chamberland，什么时候所有多项式真实和独特的零是什么？阿米尔。数学。每月。 127（2020）449-451]隐式包含在实线上正交多项式理论的基本知识中。
The purpose of this note is to point out that the main result of [M. Chamberland, When Are All the Zeros of a Polynomial Real and Distinct? Amer. Math. Monthly. 127 (2020) 449-451] is implicitly contained in the elementary lore of the theory of orthogonal polynomials on the real line.
