Question

simplify X (y-z) + 2y ( z- X) + z (x -y)​

Answer 1

Step-by-step explanation:

xy-xz+2yz-2xy+zx-zy

-xy+yz

-xy=-yz

xy=yz

x=z is the answer of this question

Answer 2

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

xy - xz + 2yz - 2yx + zx - zy. (-xz+xz=0)

xy - 2yx - xz + xz + 2yz - yz

- xy + yz

- xy = - yz

On Comparing both side,

xy = yz

x = z. ( y is taken common on both sides)
