Answer:

Step-by-step explanation:
Given
List of Options
Required
Which of the options has a degree of 2
The general format of a polynomial is

<em>Where n represents the degree </em>
In this case;
n = 2
Substitute 2 for n in expression above;





Comparing this format to the list of given options; the option with the same format is: 
Where
;
and 
<em>Hence, the polynomial with a degree of 2 is </em>
14/19 because 4 is the only number you can divide 57 and 76 and not get a decimal that is of course numbers from 1 to 10.If I am wrong let me know
