Answer 2

The solution of the given question is below .

Step-by-step explanation:

Given:

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

Using property :

$(a-b)^2=a^2+b^2-2ab\\\\(a+b)^2=a^2+b^2+2ab$

Computation:

$x^2+y^2-2xy-3x^2+3y^2+2(x^2+y^2+2xy)$

$x^2+y^2-2xy-3x^2+3y^2+2x^2+2y^2+4xy$

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

$6y^2+2xy$

The solution of the given question is $6y^2+2xy$.
