Sagot :
Answer: [tex]\pm 1, \ \pm 3, \pm 9, \pm 27[/tex]
Explanation:
Since the leading coefficient is 1, we list the factors of the last term (-27) as the list of possible rational roots. Write the plus minus version of each.
If you don't want to use the plus minus symbol, then the list could look like this:
-1, 1, -3, 3, -9, 9, -27, 27
Optionally you could sort from smallest to largest, but I think it's handy to keep the corresponding pairs together.
Answer:
p/q = ± 1/1, 3/1, 9/1, 27/1
p/q = ± 1, 3, 9, 27
Step-by-step explanation:
p comes from the list of all factors of 27.
q comes from the list of all factors of 1.
27 = 27 × 1
27 = 9 × 3
All factors of 27 are: 1, 3, 9, 27
p/q = ± 1/1, 3/1, 9/1, 27/1
p/q = ± 1, 3, 9, 27
