(a) factor (b) $k$
RECALL: (1) The factor theorem: If P(x) is divided by $x-c$ and the remainder is 0, then $x-c$ is a factor of P(x). (2) The remainder theorem states that if P(x) is divide by $x-c$, and the remainder is $k$, then $f(c)=k$. Thus, the missing expression/s in the given items are: (a) factor (b) k
