研究两个多项式的根的相对分布的显式判定问题,得出两个三次多项式的根的相对分布以及二次和四次多项式的根的相对分布的显式判定.
The relative distribution of the roots of two polynomials with symbolic coefficients is studied. We obtain the relative distribution of roots of two polynomials whose degrees are respectively 2 and 4, and we answer the same problem about the two polynomials of degree 3.
