First we add:

3x² + 2y², - x² - 4y² + 2xy and 6xy + 2x² - 3y².

3x² + 2y², - x² - 4y² + 2xy + 6xy + 2x² - 3y²

= (3x² - x² + 2x²) + (2y² - 4y² - 3y²) + (2xy + 6xy)

= 4x² - 5y² + 8xy

Now, we subtract:

- 5x² + 2y² - 3xy from 4x² - 5y² + 8xy

(4x² - 5y² + 8xy) - (- 5x² + 2y² - 3xy)

= 4x² - 5y² + 8xy + - 5x² + 2y² - 3xy

= (4x² + 5x²) + (-5y² - 2y²) + (8xy + 3xy)

= 9x² - 7y² + 11xy
