Answer: For the top equation, the answer is x^2 + 4xy + 4y^2, the bottom equation is y^2 + 4xy + 4x^2
Step-by-step explanation: The first answer was gathered from this equation
(x + 2y)(x + 2y) you multiply them together. x * x = x^2, x * 2y = 2xy, 2y * 2y = 4y^2. Now you combine like terms. x^2 + 4xy + 4y^2
For the bottom equation, we will use the same formula. (y + 2x)(y + 2x) Now, if you look at this equation, you may think it is familiar. That's because it is the same as the first equation with the x and y swapped.
So, since it is the same as the first equation, we can just swap out the appropriate terms from our first answer. y^2 + 4xy + 4x^2
