Question

6x(x – y + z) – 3y(x + y - z) from 2z(-x + y + z)​

Answer 1

Step-by-step explanation:

6x(x – y + z) – 3y(x + y - z) from 2z(-x + y + z)

Answer 2

Subtracting,

6x(x−y+z)−3y(x+y−z) from 2z(−x+y+z)

⇒ 6x

2

−6xy+6xz−3xy−3y

2

+3yz from −2xz+2yz+2z

2

= (−2xz+2yz+2z

2

)−(6x

2

−6xy+6xz−3xy−3y

2

+3yz)

= −2xz+2yz+2z

2

−6x

2

+6xy−6xz+3xy+3y

2

−3yz

= 9xy−yz−8zx−6x

2

+3y
