Add:
8a - 6ab + 5b, -6a - ab - 8b, -4a + 2ab + 3b
8a - 6ab + 5b, -6a - ab - 8b, -4a + 2ab + 3b

Answer
8a - 6ab + 5b, -6a - ab - 8b, -4a + 2ab + 3b
= 8a - 6ab + 5b + (-6a) - ab - 8b + (-4a) + 2ab + 3b
= (8a - 6a - 4a) - (6ab + ab - 2ab) + (5b - 8b + 3ab)
= -2a - (7ab - 2ab) + (8b - 8b)
= -2a - 5ab
= 8a - 6ab + 5b + (-6a) - ab - 8b + (-4a) + 2ab + 3b
= (8a - 6a - 4a) - (6ab + ab - 2ab) + (5b - 8b + 3ab)
= -2a - (7ab - 2ab) + (8b - 8b)
= -2a - 5ab
