HOPE THIS HELPS.

Answer 2

Answer:

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

= 2x + 2y +2z - 2xy - 2yz - 2xz.

Explanation:

2x +2y +2z - 2xy -2yz -2xz is the answer because there is no common term in the polynomial. Therefore, 2(x + y + z) - 2(xy + yz + xz) = 2x +2y +2z -2xy - 2yz -2xz. is the answer.

Hope this might help you........
