Ответ:
(x^2 - x + 2)(x^2 + x + 2)
Пошаговое объяснение:
====================================
х^4 + 3х^2 +4 = x^4 - x^3 + x^3 + 2x^2 - x^2 + 2x^2 + 2x - 2x + 4 =
= x^2(x^2 - x + 2) + x(x^2 - x + 2) + 2(x^2 - x + 2) = (x^2 - x + 2)(x^2 + x + 2)

х^4 + 3х^2 +4 = x^4 - x^3 + x^3 + 2x^2 - x^2 + 2x^2 + 2x - 2x + 4 =
= x^2(x^2 - x + 2) + x(x^2 - x + 2) + 2(x^2 - x + 2) = (x^2 - x + 2)(x^2 + x + 2)
