To simplify this expression, we first need to combine like terms.
The given expression is:X - xy + z - zy / 1 - 3y + 3y^2 - y^3
Now, let's combine the terms with y:
-xy - zy = (-x - z)y3y^2 - y^3 = y^2(3 - y)
Now, our simplified expression becomes:
X + (-x - z)y + z / 1 - 3y + y^2(3 - y)
This is the simplified form of the given expression.
