D. ±1 , ±1/11
Step-by-step explanation:
. The trailing coefficient (the coefficient of the constant term) is 1.
=> Find its factors (with the plus and the minus sign): ±1 (possible values of p).
. The leading coefficient (the coefficient of the term with the highest degree) is 11.
=> Find its factors (with the plus and the minus sign): ±1, ±11 (possible values of q).
. Find all possible values of p/q: ±1/1, ±1/11
. After simplifying and removing the duplicates (if any
=> ±1, ±1/11
