Killian Horne · Answer 1

If a poly has a root, r1 then a factor is (x-r1)

roots of (4-13i) and 5

factors are

(x - (4-13i)) and (x-5)

none of the above

look at them

unless you misyped

If a polynomial function f (x) has roots 4 - 13i and 5, what must be a factor of f (x) ?(x + (13 - 4i))(x - (13 + 4i))(x + (4 + 13i))(x - (4 + 13i))

(x + (13 - 4i))

(x - (13 + 4i))

(x + (4 + 13i))

(x - (4 + 13i))
