Please solve the problem fast​

Answer 1

Answer:

(x

2

−2xy+y

2

)−z

2

⇒[x(x−y)−y(x−y)]−z

2

⇒(x−y)(x−y)−z

2

⇒(x−y)

2

−z

2

⇒[(x−y)+z][(x−y)−z]

⇒(x−y+z)(x−y−z)

Answer 2

Answer:

here is your answer

x(x−y)−y(x−y)]−z²

⇒(x−y)(x−y)−z²

⇒(x−y)²-z²

⇒[(x−y)+z][(x−y)−z]

⇒(x−y+z)(x−y−z)

hopefully it helps you
