Answer 1

Answer:

$\huge\rm\pink{❥AnsWer}$

➡️ (6x² - 8xy - y² + 2xy - 2y² - x² )- (x²-5xy + 2y² + y² - 2xy - 3x² )

➡️ ( 6x² - x² - 8xy + 2xy - y² - 2y² ) - ( x² - 3x² - 5xy - 2xy + 2y² + y²)

➡️ 5x² - 6xy - 3y² - ( -2x² - 7xy + 3y²)

➡️ 5x² - 6xy - 3y² + 2x² + 7xy - 3y²

➡️ 5x² + 2x² - 6xy + 7xy - 3y² - 3y²

➡️ 7x² + xy - 6y²

Answer 2

Answer:

-7x²+2y²-13xy

Step-by-step explanation:

SUM:-

x²-5xy+2y²+y²-2xy-3x²

-5xy+2y²+y²-2xy-3x²x²-3x²+2y²+y²-5xy-2xy

-2x²+3y²-7xy

SUM:-

6x²-8xy-y²+2xy-2y²-x²

6x²-x²-y²-2y²+2xy-8xy

5x²-y²-6xy

DIFFERENCE:-

-2x²+3y²-7xy-5x²-y²-6xy

-2x²-5x²+3y²-y²-7xy-6xy

[-7x²+2y²-13xy]
