Answer 1

Answer:

x²+y²+4y5xy+3x-6xy

I have a doubt that is your questions wrong?

btw I solved it

Answer 2

Answer:

x² - y² - 3x - 4y + xy

Step-by-step explanation:

1st expression = 3x + 4y + 5xy + 20

2nd expression = ?

difference = x² - y² + 6xy + 20

• 3x + 4y + 5xy + 20 (-) ? = x² - y² + 6xy + 20

? = x² - y² + 6xy + 20 (-) 3x + 4y + 5xy + 20

? = x² - y² + 6xy + 20 - 3x - 4y - 5xy - 20

? = x² - y² - 3x - 4y + xy
