(4a^2b-3ab^2+2ab+5)+(2a^2b+3ab^2-7ab)
Combining like terms, we have:
(4a^2b - 3ab^2 + 2ab + 5) + (2a^2b + 3ab^2 - 7ab)
= 4a^2b + 2a^2b - 3ab^2 + 3ab^2 + 2ab - 7ab + 5
= (4a^2b + 2a^2b) + (-3ab^2 + 3ab^2 + 2ab - 7ab) + 5
= 6a^2b - 5ab + 5
(4a^2b - 3ab^2 + 2ab + 5) + (2a^2b + 3ab^2 - 7ab)
= 4a^2b + 2a^2b - 3ab^2 + 3ab^2 + 2ab - 7ab + 5
= (4a^2b + 2a^2b) + (-3ab^2 + 3ab^2 + 2ab - 7ab) + 5
= 6a^2b - 5ab + 5
