两个方程组实数解个数的判定

The Determination of the Number of Real Solutions of the Two Equations

摘要: 本文主要是对两个方程组的实数解的个数的判定，可知方程组(1.a)在实数范围内没有实数解，方程组(1.b)在实数范围内有四个解。

Abstract: In this paper, by determining the number of real solutions to the two equations, we can know that there is no real solution for the equations (1.a) in real numbers, and there are four solutions for the equation (1.b).
