please mark it as BRAINLIEST answer!

Step-by-step EXPLANATION:

=>(x-y)(2x-y)+(x-2y)(3x-2y)+(2x+y)(x+7y)

=>x(2x-y)-y(2x-y)+x(3x-2y)-2y(3x-2y)+2x(x+7y)+y(x+7y)

=>2x^2-xy-2xy+y^2+3x^2-2xy-6xy+4y^2+2x^2+14xy+xy+7y^2

=>(2x^2+3x^2+2x^2)+(y^2+4y^2+7y^2)+(-xy-2xy-2xy-6xy+14xy+xy)

=>(7x^2)+(12y^2)+(4xy)

=>7x^2+12y^2+4xy Ans.
