因式分解是今后求解高次方程、不等式的基础是历年中考的一个重要考点,纵观2012年全国各地的中考卷,有关因式分解的试题,主要有以下几类:一、考查因式分解的意义和有关概念例1(2012·安徽)下面的多项式中,能因式分解的是()。A.m2+n B.m2-m+1 C.m2-n D.m2-2m+1分析:根据分解因式的方法,首先是提公因式,然后考虑用公式,如果项数较多,要分组分解。本题给出四个选项中哪个可以进行因式分解,对照选项中的多项式,试用所学的方法 Factorization is to solve the higher order equation in the future. The basis of inequality is an important test center in the past years. Looking at the middle school exam papers in 2012 all over the country, there are mainly the following types of questions: The first is to examine the factorization The significance and the concept of Example 1 (2012 · Anhui) The following polynomial, can be factorized is (). A.m2 + n B.m2-m + 1 C.m2-n D.m2-2m + 1 Analysis: According to the decomposition factor method, the first is to mention the common factor, and then consider the formula, if the number of items is more , To group decomposition. This question shows which of the four options can be factorized, comparing the polynomials in the options, and experimenting with what you’ve learned
