Question

Which of the following represents the set of possible rational roots for the polynomial shown below?

Answer 1

Answer: The answer is B { +1. +2, +4, +5, +10,+20} on apex.

Step-by-step explanation:

Answer 2

You need to work out the variables of 20 (the last number) first: 
1, 2, 4, 5, 10, 20 
Lets call these folks "p" 
At that point you need to work out the components of the main coefficient (the number before the most astounding force of x): 
1 
Lets call this person "q" 
At that point you need to make all the conceivable divisions you can with: 
±p/q 
Since q is only 1, we are fortunate, so the conceivable normal roots are: 
±1/1,±2/1,±4/1,±5/1.±10/1,±20/1
