Answer:
x^2 - 5x + 4.
Step-by-step explanation:
(p - q)(x) = x^2 - 1 - (5x - 5)
= x^2 - 5x - 1 + 5
= x^2 - 5x + 4.
A number divided by 7 is 9:

Multiply both sides by 7 to get the answer so it'll be:
x = 63
8,16,24,32,40,48,56,65,73,81,88.....
9,18,27,36,45,54,63,72,81,90....
since 81 is the smallest number in both lists, it is the LCM
