在中考试卷中,常见有把一元二次方程与几何知识结合起来的综合题,解这类题目,既要运用一元二次方程的有关知识,又要注意见何图形的性质.现将这类题目的类型及解法归纳如下:一、求证两线段的长是方程的根树1已知P是直径为2的co内的一个定点,且PO一H,线段AB为过点P的任一
In the middle school test paper, there are common questions that combine the quadratic equation of one yuan with the knowledge of geometry. To solve such problems, it is necessary to use the relevant knowledge of the one-quadratic quadratic equation and the nature of the graph. The types and solutions of these types of problems are summarized as follows: First, verify that the length of the two line segments is the root tree of the equation 1 Known P is a fixed point within a diameter of 2 co, and PO-H, line segment AB is the overshoot P Any of
