中考数学试题中与二次函数相关的压轴题经常需要求面积的最大值,其求解的基本方法是“割补法”.下面举例说明.一、割例1如图1,已知抛物线y=x2+bx+c经过
In the mathematics question of the senior high school entrance examination, the quadratic function-related questions often require the maximum area, and the basic method for solving is the “Cutter Method.” The following examples are used to illustrate. A. Example 1 Figure 1 Known parabola y=x2+bx+c passes
