------>>>>Here is your answer<<<<--------

$➾(x + 2)(x - 2)( {x}^{2} + 4)$

$➾ {a}^{2} - {b}^{2} = (a + b)(a - b)$

$➾({x}^{2} - {(2)}^{2} )( {x}^{2} + {(2)}^{2} )$

$➾ {( {x}^{2} )}^{2} - { ({2}^{2}) }^{2} = {x}^{4} - 16$✓

Answer 2

Answer:

x⁴-2x²-8

Step-by-step explanation:

(x+2) (x-2) (x²+4)

x(x-2)+2(x-2) (x²+4)

x²-2x+2x-4 (x²+4)

(x²-4) (x²+2)

x²(x²+2)-4(x²+2)

x⁴+2x²-4x²-8

x⁴-2x²-8
