Answer 1

Answer:

(x2+1/x2)(x+1/x)(x-1/x)

Step-by-step explanation:

(x2)2-(1/x2)2

(x2+1/x2)(x2-1/x2)

(x2+1/x2)((x)2-(1/x)2

(x2+1/x2)(x+1/x)(x-1/x)

Answer 2

$= > {x}^{4} - \frac{1}{ {x}^{4} }$

$= > ( {x}^{2} + \frac{1}{ {x}^{2} } )( {x}^{2} - \frac{1}{ {x}^{2} } )$

$= > ( {x}^{2} + \frac{1}{ {x}^{2} } )(x + \frac{1}{x} )(x - \frac{1}{x} )$

Hope this answer helps you ^_^ !
