Answer 2

Answer:

8xy - x² - 3y² + 2

Step-by-step explanation:

Let the unknown number be z

(-8xy + 2x² + 3y²) - (z) = x² + 2

- z = (-8xy + 2x² + 3y²) - (x² + 2)

- z = -8xy + 2x² + 3y² - x² - 2

- z = -8xy + 2x² - x² + 3y² - 2

- z = - 8xy + x² + 3y² - 2

z = - (- 8xy + x² + 3y² - 2) [To remove the " - " sign from z]

z = 8xy - x² - 3y² + 2
