Question

What could be the answers to this question? It’s very confusing!

Answer 1

Answer:

First is $x^{2} +4xy+4y^{2}$

Second is $y^{2} +4xy+4x^{2}$

Step-by-step explanation:

Open up equations and do FOIL method.

First equation:

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

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

$x^{2} +4xy+4y^{2}$

Second equation:

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

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

$y^{2} +4xy+4x^{2}$
