Answer 2

Answer:

The sum of is 17pq - 3qr - 4p

Step-by-step explanation:

(8pq - 2pr - 3 q r ) + (2 r p-4 p +9pq)

8pq -2pr -3q r +2rp -4p +9pq

We take like terms together,

8pq+9pq -2pr  +2pr - 3qr - 4p

Now we add the coefficient of pq  which is equal to 17,-2 pr and +2pr cancelled out as there sum is 0.

17 pq - 3qr -4p
