Q9 CORRECT solution.
First do Long division in terms of p and q.
The equate remainder in terms of p and q to 5X+6.
You realise then that coefficient of X in terms of p and q will equal to 5
While the constant in terms of p and q will equal to 6.
Then solve.
Apologise for the wrong solution above.

Q9 answer. Form the equation first then sub in values of X. I used 1 and 2, but you can use any value you like.
Note: do not use X=0 as it will make p and q disappear

Q10 answer. Do Long division first so obtain the remainders.
Since the remainders are equal, you equate them first.
Although it may seem like you will not be able to obtain P by itself.
When expanding out P and equating the 2 remainders, you realise the square of P will cancel each other out and leave you with P only.
