Solution

$1) (12 a - 9 a b + 5 b - 3) - (4 a - 7 a b + 3 b + 12) = 8 a - 2 a b + 2 b - 15$

$2) (5 x y - 2 y z - 2 z x + 10 x y z) - (3 x y + 5 y z - 7 z x) = 2 x y - 7 y z + 5 z x + 10 x y z$

$3) (18 - 3 p - 11 q + 5 p q - 2 p q^{2} + 5 p^{2} q) - (4 p^{2} q - 3 p q + 5 p q^{2} - 8 p + 7 q - 10) = 28 + 5 p - 18 q + 8 p q - 7 p q^{2} + p^{2} q$
