Answer:
The result is X-4
and the rest is 4
Explanation:
You need to divide step by step
first the quadratic term

-
-2X------>(X-2)·x---- x is the result
-----------------------------------
2X-6X
-4X
Now divide the linear term
-4X+8---------------------->(X-2)·(-4)--- -4 is the result
---------------------------------------
-8+12
4
You cant continue so the rest is 4
Coeficient= X-4
