Question

Simplify
a) Add 3x(z-2x-y) and 3y(z-2y-x)​

Answer 1

Answer:

Add :

$3x(z - 2x - y) + 3y( z - 2y - x)$

$3xz - 6 {x}^{2} - 3xy + 3yz - 6y {}^{2} - 3yx$

$= 3xz - 6 {x}^{2} - 6xy + 3yz - 6 {y}^{2}$

Answer 2

3x (z- 2x-y ) + 3y(z-2y-x)=3x square(zsquare - 2xy- y square) = 3xy square -zsquare - 2xy - yxsquare... please mark me in brainlist
