Special Case 2 If all the coefficients in any row become all zero, that indicate poles in mirror image with respect to the origin. The evaluation can be continued by forming an auxiliary polynomial,by taking the coefficients of the last non-zero row. The all-zero row is then replaced by the coefficients of the derivative of the auxiliary polynomial.Special Case 2 • If all the coefficients in any row become all zero, that indicate poles in mirror image with respect to the origin. • The evaluation can be continued by forming an auxiliary polynomial, by taking the coefficients of the last non-zero row. • The all-zero row is then replaced by the coefficients of the derivative of the auxiliary polynomial
