A)The quantity in Column A is greater.
B)The quantity in Column B is greater.
C)The two quantities are equal.
D)The relationship cannot be determined from the information given.
Col. A: \((x+2)^2\)
Col. B: \((x-2)^2\)
Col. A: \(x^2 + 4x + 4\)
Col. B: \(x^2 - 4x + 4\)
Subtracting \(x^2\) and \(4\) from both the sides and then dividing by \(4\);
Col. A: \(x\)
Col. B: \(-x\)
When x is +ve, Col. A > Col. B
When x is -ve, Col. A < Col. B
Hence, option D

if x=0, both quantities are equal. if x=2, Quantity A is greater. So Equal & Unequal>>>> Option D
