Adding a negative interference is the same as subtracting a positive integer
The given expression is

The exponent of x is decreasing and y in increasing .
That is ,

Where a,b,c,d,e,f,g,h,i are th constants
So the correct options are b and d .
Answer:1+1×2=4
Step-by-step explanation:
1 +1 =2 ×2 =4
<u>Answer-</u>

<u>Solution-</u>
Given expression is 
Applying Binomial Theorem

Here,
a = x, b = 2 and n = 4
So,

Expanding the summation
