Nearest Singular Polynomials

The nearest singular polynomials to a given polynomial have been studied in [1], based on minimization of quadratic forms. An equivalent expression of the quadratic form is presented. It leads to a simple equation satisfied by the double zeros of the nearest singular polynomials. The amount of computational work is economized.
