在解一元二次方程或运用一元二次方程解决问题时,如果能运用整体思维,把注意力放在方程的整体结构或未知数的特征上;从宏观上整体认识问题的实质,把一些看似独立,而实际上又相互紧密联系的条件整体处理,可以避开细节的纠缠,直奔主题,而出奇制胜.下面举例说明.一、整体计算例1解方程(4x-3)~2=(3x-2)~2.
When solving a one-quadratic equation or using a quadratic equation to solve a problem, if one can use holistic thinking and focus on the overall structural or unknowns characteristics of the equation, we can understand the essence of the problem as a whole macroscopically, Independent, but in fact closely integrated with the conditions of the overall treatment, you can avoid the details of the entanglement, went straight to the theme, and surprisingly winning. The following examples. First, the overall calculation example 1 solution equation (4x-3) ~ 2 = (3x -2) ~ 2.
