Answer:

Option A

Step-by-step explanation:

Given function is,

[tex]f(x)=x^4-x^2-6[/tex]

Hint: [tex](-1=-3+2)[/tex] and [tex](-3)(2)=-6[/tex]

[tex]f(x)=x^4-3x^2+2x^2-6[/tex]

       [tex]=x^2(x^2-3)+2(x^2-3)[/tex]

       [tex]=(x^2+2)(x^2-3)[/tex]

[tex]f(x)=(x^2+2)(x^2-3)[/tex] is the factored form of the given function.

Option A will be the correct option.
