Please mark me as a brain list answer

Answer 2

Answer:(x-y+3z)(x-y-3z)

Step-by-step explanation:(x+y)^2-4xy-9z^2

(x+y)^2 is x^2+y^2+2xy-4xy-9z^2

x^2+y^2-2xy-9z^2

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

(x-y)^2-9z^2

9z^2 can also be written as (3z)^2

(x-y)^2-(3z)^2

apply the property of (a)^2-(b)^2

(x-y+3z)(x-y-3z)
