针对在中学数学课本中求一元二次方程近似根的题目,当学生学习了二次函数及其图象性质以后,可以采用本文提出的关于一元二次方程ax~2+bx+c=0(a≠0)的近似根的一种创新求法——使用区间套逼近曲线零点的方法求一元二次方程的近似根。一、求一元二次方程ax~2+bx+c=0(a≠0)近似根的方法
For the problem of solving the approximate root of the one-dimensional quadratic equation in the middle school mathematics textbook, after the student has studied the quadratic function and its image properties, the quadratic equation ax~2+bx+c=0 (which is proposed in this paper) can be used. An Innovative Approach to the Approximate Root of a ≠ 0 —— ——Using Interval Sets to Approach the Curve Zeros to Find the Approximate Root of the Unary Quadratic Equation. A method to find the approximate root of a quadratic equation ax~2+bx+c=0(a≠0)
