Answer 1

Hey frnd here is ur solution
$= \frac{ {x}^{4} - 81}{2 {x}^{2} - 5x - 3} \\ = \frac{({ {x}^{2} } )^{2} - {(9)}^{2} }{2 {x}^{2} - 6x + 1x - 3 } \\ = \frac{( {x}^{2} + 9)( {x}^{2} - {3}^{2} )}{2x(x - 3) + 1(x - 3)} \\ = \frac{( {x}^{2} + 9)( x + 3)(x - 3) }{(2x + 1)(x - 3)} \\ = \frac{( {x}^{2} + 9)(x + 3) }{2x + 1}$
