well since it flip over the x-axis only, the 8 stays the same, however, the 7 flips completely to the second quadrant and becomes -7.
Hope this helped and have a amazing day.
Our function is:

Now, if
is a factor of
then
must satisfy the equation:
So, 
Putting 
We get,




So, the value of 'a' for the given expression is 1281.
A(b-c)=d solution is number 2. Attachment added
