In the expansion of if the sum of the coefficients of and is , then is equal to
Determine the value of
Step 1: Determine the coefficients
We know that in the expansion of , term is given as :
Now for coefficients of substituting we get,
The coefficients of is
Similarly coefficients of substituting we get
The coefficients of is
Step 2: Determine the value of
According to question: coefficients of + coefficients
Hence, option C is correct .
