Answer:

[tex]x^{4}[/tex] - 256

Step-by-step explanation:

Each term in the second factor is multiplied by each term in the first factor, that is

x²(x² - 16) + 16(x² - 16) ← distribute both parenthesis

= [tex]x^{4}[/tex] - 16x² + 16x² - 256 ← collect like terms

= [tex]x^{4}[/tex] - 256

Answer:

Step-by-step explanation:

(x²+16)(x²-16) = (x²)² - 16² = x^4 - 256 use identity a²-b² = (a-b)(a+b)
