Answer: 4p + 18q - 5m - 6 + 7m²

<u>Step-by-step explanation:</u>

(4p + 2q) - (2m - 7q + 5) + (7m² - 3m + 9q - 1)

distribute the negative sign:

4p + 2q - 2m + 7q - 5 + 7m² - 3m + 9q - 1

group the like terms:

4p + (2q + 7q + 9q) + (-2m - 3m) + (-5 - 1) + 7m²

combine like terms:

4p + 18q - 5m - 6 + 7m²
