Question

What should be subtracted from x2 + y2-2xy to get x2+y2 ?​

Answer 1

Step-by-step explanation:

Let m should be subtracted from x

2

−xy+y

2

−x+y+3 to obtain −x

2

+3y

2

−4xy+1

x

2

−xy+y

2

−x+y+3−m=−x

2

+3y

2

−4xy+1

m=x

2

−xy+y

2

−x+y+3+x

2

−3y

2

+4xy−1

m=2x

2

−2y

2

+3xy−x+y+2
