Answer:

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

Explanation:

From the expression, we can rewrite to:


\displaystyle{2(x+y)-(x^2-y^2)}

From x² - y², we can apply the difference of two squares law where:


\displaystyle{x^2-y^2=(x+y)(x-y)}

Thus,


\displaystyle{2(x+y)-(x^2-y^2) = 2(x+y)-(x+y)(x-y)}}

In the expression of 2(x+y) - (x+y)(x-y), there is the same (x+y). Factor (x+y) out of the expression, therefore:


\displaystyle{2(x+y)-(x+y)(x-y)}\\\\\displaystyle{= (x+y)\left[2-(x-y)\right]}\\\\\displaystyle{=(x+y)(2-x+y)}

Hence, the factored expression is (x + y)(2 - x + y)
