Question

Which of the following are factors of x^4 – 16? Select all that apply.

Answer 1

A and D.

Explanation:

`x^4 -16`

`(x^3+2x^2+4x+8)(x-2)`

`(x^2+4)(x+2)(x-2)`

Answer 2

Answer:

x^2+4 and X+2

Solution,

x^4-16

= (X^2)^2-(4)^2

Use the formula(a^2-b^2)

= (x^2+4)(x^2-4)

=(x^2+4)(x^2-2^2)

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

Hope it helps
