Question

check whether the polynomial f(t) =4t³ +4t³-t-1 is a multiple of 2t+1​

Answer 1

Answer:

Step-by-step explanation:

just put -1/2 in f(t) if it comes zero it is multiple otherwise not

Answer 2

Answer:

f(t) is not a multiple of 2t+1

Step-by-step explanation:

f(t)=4t^3+4t^3-t-1

= 8t^3-t-1

g(t)=2t+1

t = - 1/2

f(-1/2) = 8(-1/2)^3-(-1/2)-1

        = 8(-1/8) + 1/2 - 1

        = -1 + 1/2 - 1

        = (-4+1)2

        = -3/2
