Multiply and then verify: -3x^2y^2 and (x - 2y) for x = 1 and y = 2.

(\-3x 2 y 2 ) (x \- 2y) = (\-3x 2 y 2 ) x \- (\-3x 2 y 2 ) 2y = (\-3x (2+1) y 2 ) \- (\-6x 2 y (2+1) ) = \-3x 3 y 2 \+ 6x 2 y 3 For x = 1 and y = 2 (\-3x 2 y 2 ) (x \- 2y) = \-3x 3 y 2 \+ 6x 2 y 3 Taking LHS: (\-3x 2 y 2 ) (x \- 2y) = (\-3 x 1 2 x 2 2 ) x (1 \- 2 x 2) = (\-3 x 1 x 4) x (1 \- 4) = (\-12) x (\- 3) = 36 Now, taking RHS: \-3x 3 y 2 \+ 6x 2 y 3 = \-3 x 1 3 x 2 2 \+ 6 x 1 2 x 2 3 = \-3 x 1 x 4 \+ 6 x 1 x 8 = \-12 \+ 48 = 36 Hence, LHS = RHS.
