2 x (z - x - y) + 2y (z - y - x ) answer add​

Answer 1

First expression = 2x (z − x − y) = 2xz − 2x2 − 2xy Second expression = 2y (z − y − x) = 2yz − 2y2 − 2yx Adding the two expressions, we obtain Therefore, the sum of the given expressions is − 2x2 − 2y2 − 4xy + 2yz + 2zx.

Answer 2

Answer:

= 2z - 2x - 2y + 2yz - 2y^2 - 2xy

Step-by-step explanation:

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

= 2z - 2x - 2y + 2yz - 2y^2 - 2xy
