The rational root theorem states that the rational roots of a polynomial can only be in the form p/q, where p divides the constant term, and q divides the leading term.
In your case, both the leading term 5 and the constant term 11 are primes, so their only divisors are 1 and themselves.
So, the only feasible solutions are

For the record, in this case, none of the feasible solutions are actually a root of the polynomial.
 
        
             
        
        
        
Answer:

Answer:
see explanation
Step-by-step explanation:
These are the terms of a geometric sequence with n th term
 = a
 = a
Where a is the first term and r the common ratio
r =  =
 =  =
 =  = 2
 = 2
and a = 5, hence explicit equation is
 = 5
 = 5
