Answer 1

Here is the answer
I don't understand exactly
But still I have tried
If u don't understand no need to mark as branliest..

Answer 2

Hi friend ✋✋✋✋

Your answer
--------------------

x² + 2xy + y² - a² + 2ab - b²

=> (x + y)² - (a² - 2ab + b²)

=> (x + y)² - (a - b)²

Using identity p² - q² = (p + q)(p - q).

=> { (x + y) + (a - b)} {(x + y) - (a - b)}

=> (x + y + a - b)(x + y - a + b)
