一、代数综合题 解代数综合题的关键在于对数学思想与方法的把握 ,对条件与结论之间道路的铺设 .在解题过程中需全面地、整体地处理随时发生的信息 .1 数形结合数形结合就是把“数”与“形”辩证统一地使用 ,使“形”与“数”互相交融 .例 1 已知二次函数ｙ1=ｘ2 - 2ｘ - 3.(
1. The key to solving synthetic algebraic problems in algebraic synthesis problems lies in the mastery of mathematical ideas and methods, and the laying of the road between conditions and conclusions. In the process of solving problems, it is necessary to comprehensively and integrally deal with the information that occurs at any time.1. The combination of number and shape is to use “number” and “shape” dialectically and uniformly, so that “shape” and “number” will blend with each other. Example 1 Known quadratic function y1 = x2 - 2x - 3. (
