Given,

The expression (-x-y+z)² is given.

To find,

We have to find the value of  (-x-y+z)².

Solution,

The value of (-x-y+z)² is x² +y² +z² +2xy -2yz -2zx.

We can simply find the value of (-x-y+z)² by using the algebraic identity,

(a+b+c)² = a² + b² + c² +2ab + 2bc + 2ca

a = -x, b = -y, c = z

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

             = x² +y² +z² +2xy -2yz -2zx

Hence, the value of (-x-y+z)² is x² +y² +z² +2xy -2yz -2zx.
