Answer :

Answer:

First is [tex]x^{2} +4xy+4y^{2}[/tex]

Second is [tex]y^{2} +4xy+4x^{2}[/tex]

Step-by-step explanation:

Open up equations and do FOIL method.

First equation:

(x + 2y)(x + 2y)

x^2 + 2xy + 2xy + 4y^2

[tex]x^{2} +4xy+4y^{2}[/tex]

Second equation:

(y + 2x)(y + 2x)

y^2 +2xy + 2xy + 4x^2

[tex]y^{2} +4xy+4x^{2}[/tex]
