  (a)  (x - 1) (x + 1) (x + i) (x - i)

Step-by-step explanation:

Perhaps you want the fully factored form.

The difference of squares is factored as ...

  a² -b² = (a -b)(a +b)

Your expression can be considered to be the difference of squares ...

  (x²)² -(1)² = (x² -1)(x² +1)

Each of these factors can be considered to be the difference of squares:

  x² -1 = (x -1)(x +1)

  x² +1 = x² -(i²) = (x -i)(x +i)

So, the fully factored form is ...

  x^4 -1 = (x -1)(x +1)(x -i)(x +i)
