Hey mate..
=========
Given ,
x^4 + 4
= (x^4 + 4x^2 + 4) – 4x^2
= (x^2 + 2)^2 – (2x)^2
= (x^2 + 2 + 2x)(x^2 + 2 – 2x)
= (x^2 + 2x + 2)(x^2 – 2x + 2).
Hope it helps !!

x^4 + 4
adding and substacting 4x^2 on both sides we get
(x^4 + 4 + 4x^2) - 4x^2
this becomes (x^2 + 2)^2 - (2x)^2
now by using identity we get
(x^2 + 2 + 2x)(x^2 + 2 - 2x)
