Given the function f (x) = ax & # 178; + BX + C, the image passes through points a (1,0) and B (- 1,0), and B & # 178; - 4A

Given the function f (x) = ax & # 178; + BX + C, the image passes through points a (1,0) and B (- 1,0), and B & # 178; - 4A

(1) When f (x) = ax & # 178; + BX + C, the image passes through points a (1,0) and B (- 1,0),
∴f(x)=a(x-1)(x+1)=ax^2-a,
∴b=0,c=-a,
b^2-4a=-4a=0,
The conditions are inadequate
