It is known that: X & # 178; - 4x 4 and | Y-1 | are opposite numbers, then the formula [(x

X & # 178; - 4x + 4 and | Y-1 | are opposite numbers, and both numbers are greater than or equal to 0,
So x & # 178; - 4x + 4 = 0, Y-1 = 0, find x = 2, y = 1, and then substitute it into the following formula
