Your Solution:
ATQ,
• [(6p²q - 8pqr + 7p²) + (-2p²q + 3pqr)] + [(p²q + 3pqr - 5p²) + (2p²q + 9pqr - 2p²)]
= [6p²q - 2p²q - 8pqr + 3pqr + 7p²] + [p²q + 2p²q + 3pqr + 9pqr - 5p² - 2p²]
= [4p²q - 5pqr + 7p²] + [3p²q + 12pqr - 7p²]
= 4p²q + 3p²q - 5pqr + 12pqr + 7p² - 7p²
= 7p²q + 7pqr
I hope you got it.
