Factorization of the fourth power of X to the fourth power of Y in the range of complex number=
If you help me, you'd better have a process

x^4-y^4
=(x²-y²)(x²+y²)
=(x+y)(x-y)(x²+y²)
=(x+y)(x-y)(x+iy)(x-iy)

How to factorize the cubic power-1 of X in the complex set

x^3-1
=(x-1)(x^2+x+1)
=0.25(x-1)(2x+1-isqrt(3))(2x+1+isqrt(3))

What is the factorization factor in the complex number: X to the fourth power - 9

The fourth power of X-9
=(x²－3)(x²＋3)
=(x－√3)(x＋√3)(x－√3i)(x＋√3i)
