一元二次方程是中考的一个重点,把几何问题与一元二次方程结合在一起组成综合题,又是中考中的一个热点与难点.这些综合题类型较多,其中有一类常以下列两种形式出现: (1)求作以两个几何量为根的一元二次方程;
The one-dimensional quadratic equation is a key point in the examination. Combining the geometric problem with the one-member quadratic equation to form a comprehensive problem is also a hot and difficult point in the examination. There are many types of these comprehensive questions, one of which is often the following two types. The form appears: (1) A one-member quadratic equation rooted at two geometric quantities is obtained;
