Answer 1

Answer:

(2y-1) is the factor of the polynominal

Step-by-step explanation:

because when we do cubic division with fator as (2y-1).

we get reminder 0

hence (2y-1)is the factor

hope it helps mark me as brainliest

Answer 2

Answer:

its answer is 2y-1 that is option b

Step-by-step explanation:

first find out the zero of the polynomial

so

2y-1=0

2y=0+1

2y=1

y=1/2

so put the value of y as

1/2 into the equation 4y^3+4y^2-y-1

so by doing you will end up having

1/2+1-1/2-1

so its remainder is zero so it is a factor
