| Abstract: | be a polynomial with real coefficients f Zheng Shi-ming[6] and Ye Yi-cai[7] each gave an iterative method for finding all quadratic factors simultaneously. In this paper we give another iterative method, and prove that this method and those of Zheng Shi-ining[6] and Ye Yi-cai[7] are all equivalent. Finally, we report some numerical results. |
