What is the simplified form of the expression

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
