Answer 2

To simplify the expression (-a - b)^2, you need to expand it using the rule (a - b)^2 = a^2 - 2ab + b^2. In this case, a = -a and b = -b. Let's proceed with the steps:

(-a - b)^2 = (-a)^2 - 2(-a)(-b) + (-b)^2 = a^2 - 2ab + b^2

So the simplified form of the expression (-a - b)^2 is a^2 - 2ab + b^2.
