✦ Synopsis

In this paper, we construct a counter example to show that ''Theorem'' of Hyers-Ulam Stability of Flett's Point in [M. Das, T. Riedel, P.K. Sahoo, Hyers-Ulam stability of Flett's points, Applied Mathematics Letters. 16 (3) (2003), 269-271] is incorrect. At the same time, we give the correct theorem and generalize it.

We prove that if |a 1 | is large and |a 0 | is small enough, then every approximate zero of the polynomial of degree n, a n z n can be approximated by a true zero within a good error bound.
