Answer:
remainder = 16
Step-by-step explanation:
It seems as if the bulk of the division has already been done, the next step is to just subtract the two binomials to get the remainder as one would in normal long division with real numbers.
-x+12-(-x-4) (original expression)
-x+12+x+4 (distribute the negative)
16 (combine like terms)
The remainder of the division would be 16.
