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 )
