y=a＋bx＋cx²=c(x²+bx/c)+a =c(x+b/2c)²+a-b²/4c 所以-b/2c=5，a-b²/4c=0 a+b+c=-4 a+2b+4c=-3 b+3c=-7 b=-7-3c 得7+3c=10c，c=1，b=-10 a-b²/4=0，a=25 ...

【答案】(1)-;(2)见解析;(3)a=2或a=﹣2,c=0 【解析】 (1)先写出x2+2x+c=0的倒方程为cx2+2x+1=0,然后把x=2代入cx2+2x+1=0可求出c的值; (2)根据判别式的意义,由方程ax2﹣2x+c=0无解得到ac>1,再写出一元二次方程ax2﹣2x+c=0的倒方程为cx2﹣2x+a=0,计算倒方程的判别式,从而得...
