Answer 1

Answer:

Step-by-step explanation:

Expansion is (x  

2

−  

x

1

​  

)  

n

 

constant term is 15th

⇒T  

15

​  

=  

n

C  

14

​  

(x  

2

)  

n−14

(−  

x

1

​  

)  

14

 

is independent of x.

⇒T  

15

​  

=  

n

C  

14

​  

x  

2n−28

.  

x  

14

 

1

​  

 

=  

n

C  

14

​  

(x  

2n−28

)(x  

−14

)

=  

n

C  

14

​  

x  

2n−42

 

For term to be independent of x exponent of x should be zero.

i.e. 2n−42=0

⇒2n=42

⇒n=  

2

42

Answer 2

$\huge\underline\mathbb\blue{Answer♡}$

x² is not a binomial..

Binomial - sum of two terms

Because it contain only one term ,so it is called monomial.
