Factor the polynomial as the product of factors that are irreducible over the real numbers. Then write the polynomial in completely factored form involving complex nonreal or imaginary numbers.

(x^2 + 22)(x^2 - 2)= 0
(x + √22i)(x - √22i)(x+√2)(x-√2) = 0
x = ± √22i or x = ± √2
(x + √22i)(x - √22i)(x+√2)(x-√2) = 0
x = ± √22i or x = ± √2
