1.本单元知识网络2.重点、难点、热点分析基本不等式的解法是本单元的重点.一元一次不等式、一元二次不等式的解法是重中之重,应熟练掌握;高次不等式一般用数轴标根法求解;分式不等式一般移项通分后转化为高次不等式.对于其它较复杂的不等式,常转化为上述不等式来解.无理不等式 1. This unit’s knowledge network 2. Key points, difficulties, and hot spot analysis The solution to the basic inequality is the focus of this module. The solutions of one-element inequalities and one-element quadratic inequalities are of utmost importance and should be mastered; high-order inequalities are generally used on several axes. Standard root method; Fractional inequalities are generally converted into high-order inequalities after transposition. For other more complex inequalities, often converted to the above inequalities to solve. Unreasonable inequalities.
