 ( {x}^{2}  + 9)(x - 3)

Step-by-step method : -

 \frac{ {x}^{4}  - 81}{x + 3}

 =   \frac{ { {(x}^{2}) }^{2} -  {9}^{2}  }{x + 3}   \\  =  \frac{( {x }^{2} + 9)( {x}^{2}  - 9) }{x + 3}  \\  =  \frac{( {x}^{2} + 9)( {x}^{2} -  {3}^{2}  ) }{x + 3}  \\  =  \frac{( {x}^{2}  + 9)(x + 3)(x - 3)}{x + 3}  \\  = ( {x}^{2}  + 9)(x  - 3)
