Answer 3

Let's break down the expressions you provided:

1. $A^2 - B^2$: This is a difference of squares and can be factored as $(A + B)(A - B)$.

2. $(a + b)^2$: This is the square of a binomial and can be expanded as $a^2 + 2ab + b^2$.

3. $(a - b)^2$: Similarly, this is the square of a binomial and can be expanded as $a^2 - 2ab + b^2$.

So, in summary:

1. $A^2 - B^2 = (A + B)(A - B)$
2. $(a + b)^2 = a^2 + 2ab + b^2$
3. $(a - b)^2 = a^2 - 2ab + b^2$

If you have specific values for A, B, a, and b, you can substitute those values into the expressions to get numerical results.
