Question

find the zeroes of 6x^3+5x^2+7x-20 and verify the relation between zeroes and coefficients​

Answer 1

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.

Answer 2

Answer:

the sum of coefficients is given by f (1,1) =n ౾k =ock .

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
