Answer:
a) We get 
So, Is the result of A+B is a polynomial:Yes
b) We get 
So, Is the result of A-B is a polynomial:Yes
c) We get 
So, Is the result of A.B is a polynomial:Yes
Step-by-step explanation:
We are giving the polynomial equations:
We need to find
a) A+B
So, we get
So, Is the result of A+B is a polynomial:Yes
b) A-B
So, we get
So, Is the result of A-B is a polynomial:Yes
c) A . B
So, we get
So, Is the result of A.B is a polynomial:Yes

Total number of team in starting = 128 teams.
In each round half of the teams are eliminated.
Therefore, number of teams remain after first round = 128/2 = 64.
The number of teams remain after second round = 64/2 = 32.
The number of teams remain after third round = 32/2 = 16.
The number of teams remain after fourth round = 16/2 = 8.
The number of teams remain after fifth round = 8/2 = 4.
<h3>Therefore, after 5 rounds there remain only 4 teams.</h3>
I think x = -12 , if that’s what the questions asking
