在全国各省市的中考数学试中 ,代数解答题大致可分以下几种类型 :一、因式分解 ;二、化简、求值 ;三、解方程 (组 )、不等式 (组 ) ;四、函数问题 ;五、以一元二次方程或二次函数为载体的综合应用问题 .一般说来 ,前四类问题的难度不大 ,多为“送”分的中档题 ;后一类问题比较 In the middle school mathematics test of various provinces and cities across the country, the algebraic answer questions can be roughly divided into the following types: 1. factorization; 2. simplification and evaluation; 3. solution equations (groups) and inequalities (groups); Function problems; Fifth, the comprehensive application of the quadratic equation or quadratic function as the carrier. Generally speaking, the first four kinds of problems are not difficult, mostly “delivery” points in the mid-range problem; the latter type of problem comparison
