Answer 2

It looks like you're asking about the expression (2 + m)^2 * (2 - m)^2. To simplify this expression, you can expand both squared terms and then multiply them together. Let's go through the steps:

First, expand (2 + m)^2: (2 + m)^2 = (2 + m) * (2 + m) = 4 + 2m + 2m + m^2 = 4 + 4m + m^2

Next, expand (2 - m)^2: (2 - m)^2 = (2 - m) * (2 - m) = 4 - 2m - 2m + m^2 = 4 - 4m + m^2

Now, multiply the two expanded terms: (4 + 4m + m^2) * (4 - 4m + m^2)

Use the distributive property (FOIL method) to multiply the terms: = 4 * 4 + 4 * (-4m) + 4 * m^2 + 4m * 4 + 4m * (-4m) + 4m * m^2 + m^2 * 4 + m^2 * (-4m) + m^2 * m^2 = 16 - 16m + 4m^2 + 16m + (-16m^2) + 4m^3 + 4m^2 - 4m^3 + m^4

Combine like terms: = 16 + 4m^2 - 16m^2 + m^4 = 16 - 12m^2 + m^4

So, the simplified expression is 16 - 12m^2 + m^4.
