Answer 2

Answer:

$-6x^2-2xy-3y^2$

Step-by-step explanation:

Sorry I'm late, I made a mistake and erased whole explanation.

$(x + 2y) (- 3x - y) - (x + y) (x - y) + (x - 2y) (- 2x + y)\\=(-3x^2-xy-6xy-2y^2)-(x^2+xy+xy-y^2)+(-2x^2+xy+4xy-2y^2)\\=-3x^2-7xy-2y^2-x^2+y^2-2x^2+5xy-2y^2\\=(-3-1-2)x^2+(-7+5)xy+(-2+1-2)y^2\\=-6x^2-2xy-3y^2$

∴$-6x^2-2xy-3y^2$
