The expression 2x - (xy + 1)² – 2 evaluated for the values of the variables is -13

How to evaluate the expression for the values of the variables

From the question, we have the following parameters that can be used in our computation:

x = -1, y = 4 and z = -2.

Also, we have

2x - (xy + 1)² – 2

Substitute the known values into the equation

2x - (xy + 1)² – 2 = 2 * -1 - (-1 * 4 + 1)² – 2

Evaluate

2x - (xy + 1)² – 2 = -13

Hence, the expression evaluated for the values of the variables is -13
