一元二次方程是一元一次方程的延续,又是二次函数学习的基础,深入探究一元二次方程会更进一步推动我们对方程概念内涵的再认识,可以解决更多的以前我们无法解决的问题,也将为我们学习其他知识带来更大的方便。初中阶段对一元二次方程的学习要求:能根据具体问题中的数量关系,列出一元二次方程,体会一元二次方程的概念,理解配方法,能用配方法、公式法、因式分解法解数字系列的一元二次方程,能根据具体问题的实际意义,检验一元二次方程的解
The quadratic equation is a continuation of a linear equation, which is also the basis of quadratic function learning. Studying the quadratic equation further will further promote our understanding of the connotation of the equation and solve more problems that we could not solve before , Will also bring more convenience for us to learn other knowledge. Junior high school on the quadratic equation of the learning requirements: According to the specific relationship between the number of questions, lists the quadratic equation quadratic, understand the concept of a quadratic equation to understand the formula method, the formula can be used, the formula method, factorization The solution to the digital series of quadratic equations, according to the practical significance of the specific problem, test the solution of a quadratic equation
