Respuesta :

The first box will be filled with [tex]x^2-2xy[/tex]

Th second box will filled with [tex]x^2+2xy[/tex]

The third box will be filled with [tex](x+y)^2[/tex]

Step-by-step explanation:

Given polynomial indentity is:

[tex](x-y)^2+4xy=(x+y)^2[/tex]

we will prove the identity one by one

So,

The first step is to open the (x-y)^2

[tex]x^2-2xy+y^2+4xy=(x+y)^2[/tex]

Combining like terms

[tex]x^2-2xy+4xy+y^2=(x+y)^2\\x^2+2xy+y^2=(x+y)^2\\[/tex]

Closing the formula

[tex](x+y)^2=(x+y)^2[/tex]

Considering the above proof

The first box will be filled with [tex]x^2-2xy[/tex]

Th second box will filled with [tex]x^2+2xy[/tex]

The third box will be filled with [tex](x+y)^2[/tex]
