Question

(x + y + z)(x + y – z) simplify​

Answer 1

Answer:

(x^2 + xy -xz) + ( xy + y^2-yz) + ( xz + yz- z^2)

Answer 2

Answer:

here is your answer....

x² + xy - xz + yx + y² - yz + xz + yz - z²

= x² + y² - z² + 2xy ..

= (x + y)² - z²

...( a²+b²+2ab = (a+b)² )..

= ( x+y )² - z²

hope this will help you!!!❤️
