Question

Question- 2) Add :- 2x(z-X-Y)
and 2y(z-y-x)​

Answer 1

Answer:

2xz - 2x² - 4xy - 2yz - 2y²

Step-by-step explanation:

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

(After removing the brackets)

= 2xz - 2x² - 2xy + 2yz - 2y² - 2xy

(After rearranging the like term)

= 2xz - 2x² - 2xy - 2xy - 2yz - 2y²

(After solving the like term)

= 2xz - 2x² - 4xy - 2yz - 2y²
