according to the question, we have to subtract g(y) from f(y) and then we have to find the degree of the resultant polynomial.
given :-
f(y) = 6y² - 7y + 2
g(y) = 7y + y³
= (6y² - 7y + 2) - (7y + y³)
= 6y² - 7y - 7y + 2 + y³
= 6y² - 14y + 2 + y³
= y³ + 6y² - 14y + 2
3 is the degree of resultant polynomial as it's the highest power here.

Hi ,
It is given that ,
F( y ) = 6y² - 7y + 2 ,
f( y ) = 7y + y³
Let the resultant polynomial p(y)
p( y ) = F( y ) - f( y )
= 6y² - 7y + 2 - ( 7y + y³ )
= 6y² - 7y + 2 - 7y - y³
p( y ) = - y³ + 6y² - 14y + 2
Therefore ,
Required Resultant polynomial
= p( y ) = - y³ + 6y² - 14y + 2
Degree of p( y ) = Heighest power
of y in p( y )
= 3
I hope this helps you.
