X^4 + 4
= (x^2)^2 + 2×x^2×2 +(2)^2
= (x^2)^2 + 2×x^2×2 +(2)^2

Factoring: x4-4
Theory : A difference of two perfect squares
A2 - B2 can be factored into (A+B) • (A-B)Proof : (A+B) • (A-B) =A2-AB + BA - B2 =A2- AB + AB- B2=A2- B2Note : AB = BA is the commutative property of multiplication.
Note : - AB + ABequals zero and is therefore eliminated from the expression.
Check : 4 is the square of 2
Check : x4 is the square of x2 Factorization is : (x2+ 2) • (x2- 2)
