which function below, if either, has zeros that are complex conjugates?
P(x)= X^47x^327x^2+63x+81
H(x)=x^3x^2+25x25

H(x) = x^2(x1) + 25(x1)
= (x1)(x^2 + 25)
for zeros,
(x1)(x^2 + 25) = 0
x = 1, or x = ±5i
±5i are complex conjugates
Off hand, I can't see any for the first one. 
what do you mean

complex conjugates are numbers of the form
a+bi and abi
±5i can be written as
0+5i and 05i, which fits the above form.
