$\textit{\large{\underline{\underline{\pink{Step by step Explanation:-}}}}}$

${x}^{8} - 1 \\ = {x}^{8} - {1}^{8} \\ = (x {}^{4} ) {}^{2} - (1 {}^{4} ) {}^{2} \\ = ( {x}^{4} + {1}^{4} )( {x}^{4} - {1}^{4}) \\ = ( {x}^{4} + 1)( {x}^{4} - 1)$

By using identity,,

$\mathit{\boxed{\red{a^{2}-b^{2}=(a+b)(a-b)}}}$
