一元二次方程是初中数学中的重要内容,学好这部分内容对今后学习二次函数、一元二次不等式等知识起着至关重要的作用.本文举例说明一元二次方程习题的解题思路,供同学们学习时参考.一、关于一元二次方程的解法一般地解一元二次方程有四种方法,即因式分解法、开平方法、配方法、公式法,这四种方法各有特色,但基本思想相同,都是降次.使用哪种方法简便,要依具体 Unary quadratic equation is an important part of junior high school mathematics, and learning this part plays a crucial role in learning quadratic functions, unary quadratic inequalities and other knowledge in the future.This paper gives an example of solving the problem of solving quadratic equations, For students to learn reference.One, on the quadratic equation solution General solution to the quadratic quadratic method there are four methods, namely, factorization, Kaiping method, with the formula, the formula method, these four methods have their own characteristics , But the basic idea is the same, are reduced times. Which method is easy to use, according to the specific
