(4p ^ 3q ^ 7 - 12p ^ 4 q ^ 7 + 3pq )  + (7p ^ 4 q ^ 7 + 9p ^ 3  q ^ 7 - 3pq)= 13 p ^ 3  q ^ 7 - 5p ^ 4 q ^ 7

Step-by-step explanation:

(4p ^ 3q ^ 7 - 12p ^ 4 q ^ 7 + 3pq )  + (7p ^ 4 q ^ 7 + 9p ^ 3  q ^ 7 - 3pq)\\=  4p ^ 3q ^ 7 - 12p ^ 4 q ^ 7 + 3pq  + 7p ^ 4 q ^ 7 + 9p ^ 3  q ^ 7 - 3pq \\=4p ^ 3q ^ 7+ 9p ^ 3  q ^ 7- 12p ^ 4 q ^ 7 + 7p ^ 4 q ^ 7 + 3pq    - 3pq\\=(4+ 9)p ^ 3  q ^ 7(- 12 + 7)p ^ 4 q ^ 7\\= 13 p ^ 3  q ^ 7 - 5p ^ 4 q ^ 7
