Which expression has the same value as −3 + (−5)?
a −5 + (−3)
b −3 − (−5)
c −5 − (−3)
d −3 + 5

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.
