Answer:
Here the concept of reminder theorem can be used.
this theorem states that the reminder when f(x) is divided by (x-a) is f(a).
let
f(x)= x
2
- ax
2
+8x+a
We can find f(a) by substituting 'a' in the replace of x in the above equation.
f(a)= a
2
- a×a
2
+8a+a
f(a)= a
2
- a
3
+9a
Hence the reminder is a
2
- a
3
+9a
