If (x + 8) is a factor of f(x), which of the following must be true? Both x = -8 and x = 8 are roots of f(x).
Neither x = -8 nor x = 8 is a root of f(x).
fl-8)=0
f(8) = 0

is a root.

is correct.

Step-by-step explanation:

As

is a factor of

then it must be

is a root.

Therefore,

is correct.

i think it might be a but you might want a second opinion
