pls explain it also I mark you brainliest
and give you thanks​

Answer 1

may be this will the right answer and this help you

Answer 2

the answer is -6x^2-2xy-5y^2.

Step-by-step explanation:

(x+2y) (-3x-y) -(x+y) (x-y)+(x-2y) (-2x+y)

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

= -3x^2-7xy-2y^2-(x^2-y^2)+(-2x^2+5xy-2y^2)

= -3x^2-7xy-2y^2-x^2+y^2-2x^2+5xy-2y^2

= -6x^2-2xy-5y^2

I hope this will help you!!!
