Tip:
-When (x+1) is a factor, it means that f(-1) = 0
- For qn 5, f(-1) = 0 and f(0.5) =0, use simultaneous equation to solve for p & q.
-Afterwards, use division method to show that there is a remainder for (x-3) OR show that f(3) not equal to 0
- For qn7, solve for k when f(k) = 0. Then we can divide f(x) by (x-k) once we know what is k
