因式分解是初中代数的重要内容之一,因此,在全国各省市历年的中考数学试题中,都少不了因式分解这一内容,甚至有些省市年年考,如北京市自1985年至1993年的中考,年年都有分解因式的考题.有些省市的中考试卷中,虽然表面上没有分解因式的题目,但在化简、求值和解方程等题中也都间接地考到这一方面的知识.因此,熟练地掌握因式分解的方
The factorization is one of the important contents of junior high school algebra. Therefore, in the mathematics examination questions of the provinces and cities across the country in the years of mathematics, there is no question of factorization, and even some provinces and cities annually, such as Beijing from 1985 to 1993. In the middle school exams of the year, there are decomposing factor tests each year. In some examination papers of provinces and cities, although there is no factor on the surface of the factor, there are also indirect examinations in questions such as simplification and evaluation of equations. Knowledge in this area. Therefore, mastery of factorization
