Step-by-step explanation:
-2(x² - y² + xy) - 3(x² + y² - xy)
-2(x² - y² + xy) - 3(x² + y² - xy)= -2x² +2y² -2xy -3x² -3y² +3xy
-2(x² - y² + xy) - 3(x² + y² - xy)= -2x² +2y² -2xy -3x² -3y² +3xy= -5x² -y² +xy
-2(x² - y² + xy) - 3(x² + y² - xy)= -2x² +2y² -2xy -3x² -3y² +3xy= -5x² -y² +xy = xy - 5x² - y²
