Answer 1

Step-by-step explanation:

(-x²-3xy + 3y² + 8) + (3x² - 5y² −3+

4xy) + (- 6xy + 2x² - 2 + y²)

= − x² − 3xy + 3y² + 8 + 3x² - 5y² - 3+ 4xy - 6xy + 2x² - 2 + y²

= -x² + 3x² + 2x² - 3xy - 6xy + 4xy + 3y² + y2 - 5y2 + 8-3-2

= 4x² - 5xy - y² + 3

Answer 2

=(2+2)x+(-6+4)xy+(3-2+2)y+(2+2)
=4x-10xy+3y+4 -ANSWER
