Trong mặt phẳng tọa độ Oxy cho Parabol (P): \(y=x^2\) và đg thg (d): \(y=2x+2m-1\) (với m là tham số)
a) Với m=0, chứng tỏ đg thh (d) và Parabol (P) có 1 điểm chung. Tìm tọa độ điểm chung đó
b) Tìm các gtri của m để (d) và (P) cắt nhau tại 2 điểm phân biệt có các hoành độ \(x_1,x_2\) thoa man đk \(x_2^2\left(x_1^2-1\right)+x_1^2\left(x_2^2-1\right)=8\)
