Question

y - x ^ 2 - y ^ 2 - 2xy is equals to..?​

Answer 1

Step-by-step explanation:

4-(x^2+y^2+2xy)

=2^2-(x+y)^2

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

Answer 2

4 - x² - y² - 2xy

2² - x² - y² - 2xy

using = a² - b² = (a+b) (a-b)

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

Hence , 4 - x² - y² - 2xy is equal to (2+x +y ) ( 2 - x-y )
