Answer:
x^4 + 324
(x^2)^2 + 18^2
That would be a perfect square if the term that is twice the product of the square roots of those two terms were added. That's 2·18·x^2 or 36x^2.
So we add that between those terms and then subtract it. That's the same as adding 0:
(x^2)^2 + 36x^2 + 18^2 - 36x^2
Factor the first three terms as (x^2 + 18)(x^2 + 18) or (x^2 + 18)^2
(x^2 + 18)^2 - 36x^2
That is the difference of two perfect squares:
[(x^2 + 18) - 6x][(x^2 + 18) + 6x]
[x^2 + 18 - 6x] [x^2 + 18 + 6x]
(x^2 - 6x + 18) (x^2 + 6x + 18)..
