P-3q+8=5。

So p-3q=-3, which means 3q-p=3.

P is not equal to 3 because the original formula is cubic and quartic.

Because pq is a positive integer, they have the same sign, and p is a multiple of 3.

If they are all positive numbers, the minimum value of p is 6, q=3, pq= 18.

If they are all negative numbers, the absolute value of p is at least -3 and q=0, which is impossible; Therefore, p=-6, q=- 1 and pq=6, so choose this case.

Therefore, three, two, one (quadratic term coefficient) and constant term are -9, 5, 6 and -8 respectively.
