Answer 1

Respuesta:

$( {x}^{2} - 9)( {x}^{2} {y}^{2} + 1)$

Explicación paso a paso:

${x}^{4} {y}^{2} - 9 {x}^{2} {y}^{2} + {x}^{2} - 9 =$

$( {x}^{4} {y}^{2} + {x}^{2} ) + ( - 9 {x}^{2} {y}^{2} - 9) =$

${x}^{2} ( {x}^{2} + 1) - 9( {x}^{2} {y}^{2} + 1) =$

$( {x}^{2} - 9)( {x}^{2} {y}^{2} + 1)$
