Answer 3

It seems like you want to simplify the expression (1-a)^2 * (2^2 - b^2). Let's break it down step by step:

1. Start with (1-a)^2:

(1-a)^2 = (1-a)(1-a) = 1 - 2a + a^2

2. Next, simplify 2^2 - b^2:

2^2 - b^2 = 4 - b^2

3. Now, multiply the two simplified expressions:

(1-a)^2 * (2^2 - b^2) = (1 - 2a + a^2) * (4 - b^2)

4. Expand the product using the distributive property:

= 4(1 - 2a + a^2) - b^2(1 - 2a + a^2)

5. Distribute the constants and variables:

= 4 - 8a + 4a^2 - b^2 + 2ab^2 - a^2b^2

So, the simplified expression is:

4 - 8a + 4a^2 - b^2 + 2ab^2 - a^2b^2
