Question

(x²+root16)(x²-root16) identity

Answer 1

Step-by-step explanation:

(x²+√16)(x²-√16)

(x²)²-(√16)²

x⁴-16

Answer 2

$( {x}^{2} + \sqrt{16} )( {x}^{2} - \sqrt{16} ) \\ = ( {x}^{2} + 4)( {x}^{2} - 4)$

Using The Identity,

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

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