9. What is the equation of the polynomial whose zeros are - 4, and 8?

and f (x) = (x-4) (x+8)

e. f (x) = (x + 4) (x + 8)

b. f (x) = (x + 4) (x-8)

d. f (x) = (x - 1) (x-8)

Answer: b. f (x) = (x + 4) (x-8)

Step-by-step explanation:

The formula for finding equation of polynomial given the roots is given by:

f (x) = (x - α) (x - β)

where α and β are the roots of the equation

from the given question : α = - 4, β = 8, substituting into the equation, we have:

f (x) = (x - {-4}) (x - 8)

f (x) = (x + 4) (x - 8)
