Answer 2

Let's simplify the given expressions:

1. a^2 + 2ab + b^2 - (a^2 - b^2) = a^2 + 2ab + b^2 - a^2 + b^2 (distribute the negative sign) = 2ab + 2b^2 (combine like terms)

2. x^2 - 2x + 1 - (x^2 - 1) = x^2 - 2x + 1 - x^2 + 1 (distribute the negative sign) = -2x + 2 (combine like terms)

Therefore, the simplified expressions are:

1. 2ab + 2b^2
2. -2x + 2
