Which identity could be used to rewrite x^4-16

The correct answer is,

x⁴ - 16 = (x² + 4)(x + 2)(x - 2)

Step-by-step explanation:

Identity

(x² - y²) = (x + y)(x - y)

To rewrite x⁴ - 16

Using identity we can write,

x⁴ - 16 = [(x²)² - 4²]

 = (x² + 4)(x² - 4)

 = (x² + 4)(x - 2²)

 = (x² + 4)(x + 2)(x - 2)

Therefore  x⁴ - 16 = (x² + 4)(x + 2)(x - 2)
