Answer:
Quantity B is greater.
Explanation:
<u>Given</u>:
(x -2y)(x +2y) = 4
A = x² -4y²
B = 8
<u>Find</u>:
the relationship between A and B
<u>Solution</u>:
The given expression can be expanded to give ...
x(x +2y) -2y(x +2y) = x² +2xy -2xy -4y² = x² -4y²
This is precisely the expression designated as A. Its value is 4.
4 < 8
A < B
Quantity B is greater.
