Open Question: use given zero to find the remaining zeros of the polynomial?

use given zero to find the remaining zeros of the polynomial?

g(x) = x^3 + 3x^2 + 25x + 75 Zero: -5i

if one zero is (- 5i), then (5i) is also a zero

(x + 5i)(x - 5i) = x^2 + 25

long division by (x^2 + 25) yields the quotient: (x + 3)

the remaining zero is: x = - 3
