Answer:
Step-by-step explanation:
( x+y )^2 - 4xy
= (x^2 +y^2 +2xy) -4xy
= x^2 + y^2 +2xy -4xy
= x^2 + y^2 -2xy [Using the identity, (a-b)^2 = a^2 + b^2 -2ab]
= (x-y)^2

Answer:
(x - y)(x - y)
Step-by-step explanation:
(x + y)² - 4xy
=> x² + y² + 2xy - 4xy = 0
=> x² + y² - 2xy = 0
=> (x - y)² = 0
=> (x - y)(x - y) = 0
