Answer 2

$= ( { \frac{ - 1}{3} }^{2} + 3 \times \frac{ - 1}{3} - 2) - (2 \times { \frac{ - 1}{3} }^{2} + 3 \times \frac{ - 1}{3} - 1) \\ =( \frac{1}{9} - 1 - 2) - ( \frac{2}{9} - 1 - 1) \\ = ( \frac{1}{9} - 3) - ( \frac{2}{9} - 2) \\ = \frac{1}{9} - 3 - \frac{2}{9} + 2 \\ = \frac{ - 1}{9} - 1 \\ = \frac{ - 1 - 9}{9} = \frac{ - 10}{9}$
