Answer:
the sum of coefficients is given by f(1,1)=n∑k=0ck. Just write down the general formula for the binomial expansion of (a−b)n. Then consider what happens when a=b. You will see that the sum of the binomial coefficients must be equal to zero.

just write down the general formula for binomial expassion of (a,b) in .
then consider what happens when a =b.
you will see that the sum of the binomial cofficients must be equal to zero
