Given :

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

Solution :

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

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

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

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

 {x}^{4}  - 81

ans. \:  \:  {x}^{4}  - 81

Step-by-step explanation:

Here we have used a formula. The formula is :

( {a}^{2})  - ( {b}^{2} ) = (a + b)(a - b)

Using the above given formula we solved the problem.
