WebThis would be x squared plus, we can add these two coefficients because they're both on the first degree terms, they're both multiplied by x. If I have ax's and I add bx's to that I'm going to have a plus b x's. So let me write that down. a plus b x's, and then finally I have the plus, I'll do that blue color, finally I have it. Web分析:(1)抛物线y=mx 2 +nx+p与y=x 2 +6x+5关于y轴对称,即y=x 2 +6x+5上的点关于y轴的对称点在函数y=mx 2 +nx+p上,可以在y=x 2 +6x+5上取几点,求出它们关于y轴的对称点,利用待定系数就可以求出函数的解析式. (2)根据抛物线的解析式,可以求出A,B点的坐标,则C的坐标也可以求出.过点C作CD⊥BM,易证 ...
