Given:

(x-y)²-4(x-y)

To Find:

The value of the given expression.

Solution:

Expanding the given expression,

x² - 2xy + y² - 4x + 4y.

x² - 4x - xy + y² + 4y - xy.

x(x - 4 - y) + y(y + 4 - x).

x(x - y - 4) - y(x - y - 4).

(x - y)(x - y - 4).

Hence, the factors of the given expression is (x - y)(x - y - 4).
