Expanding [x+y]^2 = x^2+2xy+y^2

Since xy<0, quantity a will always have the effect of negative 2xy

Therefore quantity B will be greater

Quick and swift.

Simplify the two quantities, and cancel common terms from both sides, yielding:

Quantity A: 2xy
Quantity B: 0.

Given that xy < 0. Hence A is negative, and B is positive. Hence B is greater.
