Answer 2

Answer:

Hi there !!

Given,

To factorise x² - y² + 2x - 2y

Using the 3rd identity, ie, a²- b² = (a - b)(a + b) and taking 2 as common factor in 2x - 2y,

We have,

(x - y)(x + y) + 2(x - y)(x−y)(x+y)+2(x−y)

Taking (x - y) as common factor,

we have,

(x - y)(x + y + 2)(x−y)(x+y+2)

is the answer.
