Answer 1

Answer:

1x²-3x+3y²

3x+4xy² I think this is right

Answer 2

Answer:

x²- 3x+ y²-x-2y²​ =  x²-4 x -y²

Step-by-step explanation:

Given : x²- 3x+ y²-x-2y²​

x²- 3x+ y²-x-2y²​

Arrange like terms, we get

= x²- 3x-x + y²-2y²​

Find common and solve

= x²+(-3 -1) x + ( 1 - 2)y²

= x²-4 x -y²
