不等式性质常见的有如下三个1.不等式的两边都加上(或减去)同一个整式,不等号的方向不变.2.不等式的两边都乘以(或除以)同一个正数,不等号的方向不变.3.不等式的两边都乘以(或除以)同一个负数,不等号的方向改变.这三个基本性质是对不等式进行变形的重要依据,灵活应用它们,能帮我们顺利地解
There are three common properties of the inequality 1. The inequality adds (or subtracts) the same integral to both sides, and the direction of the inequality does not change. 2. The two sides of the inequality are multiplied by (or divided by) the same positive number, and the inequality The direction of the same .3 inequality both sides are multiplied by (or divided by) the same negative number, the direction of the inequality change.These three basic properties of the inequality is an important basis for deformation, flexible application of them, can help us smoothly solution
