x^2 - y^2 + 2yz - z^2
= x^2 - [ y^2 - 2yz + z^2]
= (x)^2 - (y - z)^2
= ( x + y - z) (x - y + z)
= x^2 - [ y^2 - 2yz + z^2]
= (x)^2 - (y - z)^2
= ( x + y - z) (x - y + z)

Answer:
Step-by-step explanation:
x^2 - y^2 + 2yx - z^2
=x^2 - (y^2 + 2yx - z^2)
=x^2 - (y - z)^2
={x^2 + (y - z)} {x^2 - (y-2)}
=(x + y - z) (x - y + z)
