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]
