Step-by-step explanation:

HEY HERE IS THE EXPLANATION FOR THE ANSWER.........


The answer is so simple that if you substitute the given values in the equation you will get your answer.

given that

     =>           x = 3 , y = 2 and z = -1                  

     =>           ( 7 x^2 y  - 3 z^ 2) (x + y + z )

     =>           ( 7*3 ^2*2 - 3*-1 ^2) (3+2-1)

     =>           [21^4 - ( -3)^2] (4)

     =>           (194481 +9)(4)                                             3 113

     =>           194490*4                                                   194490*4  

     =>            777960                                                       777960


                       hence proved
