Câu trả lời:

2x2 + 2y2 + 2xy - 4x + 4y + 8 = 0

<=> x2 + x2 + y2 + y2 +2xy -4x +4y + 4 + 4 = 0

<=> (x2 -4x + 4)+ (y2 +4y + 4) + (x2 + 2xy + y2) =0

<=> (x - 2)2 + (y + 2)2 + (x + y)2 =0

Vì (x - 2)2 >= 0 với mọi x

(y + 2)2 >= 0 với mọi y

(x + y)2 >= 0 với mọi x, y

mà (x - 2)2 + (y + 2)2 + (x + y)2 = 0

=> (x - 2)2 = 0

(y + 2)2 = 0

(x + y)2 = 0

=> x - 2 = 0

y + 2 = 0

x + y = 0

=> x = 2

y = -2

Vậy x = 2; y = -2
