(3x^2 + 4)(x - 3)(3x2 - 4)  =  (3x^2 + 4)(3x^2 - 4)(x - 3)

                                        =  [ (3x^2)^2  - (4)^2 ] (x - 3)

                                        =  [ 9x^4  - 16 ] (x - 3)

                                        =  (9x^4  - 16)x  - 3(9x^4  - 16)

                                        =  (9x^5  - 16x)  - (27x^4  - 48)

                                        =  9x^5  - 16x  - 27x^4  + 48

                                        =  9x^5 - 27x^4 - 16x  + 48

Answer :

(3x^2 + 4)(x - 3)(3x2 - 4)  =  9x^5 - 27x^4 - 16x  + 48.
