论文部分内容阅读
方程(组)的知识是初中数学的核心内容之一,也是历年中考热点.这部分知识内容涉及的考点主要有:一元一次方程、二元一次方程组、可化为一元一次方程的分式方程、一元二次方程的解法以及列方程(组)解决实际问题.一、考点内容知识脉络二、专题考点解析在中考中,考点有如下特点:(1)考查方程(组)的概念和解法的基础知识,类型常以选择题、填空题、解答题形式出现,有时也会与一次函数、不等式相结合出题;(2)一元二次方程是二次函数的一种特殊形式,两者有着密切的关系,在中考题中主要以填空题、选择
The knowledge of equations (groups) is one of the core contents of mathematics in junior high schools, and also a hot spot in the examination of the past years.Major test points involved in this part of knowledge are: a unitary equation, a system of binary equations, a fractional equation that can be transformed into a unitary equation , A quadratic equation solution and column equations (group) to solve practical problems.One, the test content Second, thematic test point analysisIn the test, the test point has the following characteristics: (1) to examine the concept of equation (group) solution method Fundamentals, types often multiple choice, fill in the blank questions, answer questions appear, and sometimes with a function, inequality combination of questions; (2) quadratic quadratic equation is a special form of quadratic function, both have Close relationship between the entrance exam in the main fill in the blank question, choose
