1. f(x)
=
2. Remember
that for (x-2) to be a factor, then when we divide f(x) by (x-2) the remainder
must equal zero.
3. Use
synthetic division to find the remainder when divided by (x-2):
2 | 1
-k
k
16
2
(4-2k) (8-2k)
1
(2-k)
(4-k)
(24-2k)
The remainder is (24-2k), so for that to equal zero, k must
equal 12.
If k=12, then the above result would be:
1
-10 -8
0
Therefore we could factor f(x) = =
f(x) =
