Answer:
±1, ±1/2, ±1/3, ±1/6, ±3 and ±3/2
Step-by-step explanation:
You need to write down all the factors of 3 and 6 so:
for 3: it's only ±1 and ±3 since it's a prime number
for 6: ±1, ±2, ±3 and ±6
so possibles 0's are factors of 3/factors of 6
So we get: ±1/1, ±1/2, ±1/3, ±1/6 and ±3/1, ±3/2, ±3/3, ±3/6
if we simplify this we get:
±1, ±1/2, ±1/3, ±1/6, ±3, ±3/2 (because ±3/3 = ±1 and ±3/6 = ±1/2)
