Answer 2

To simplify the expressions and expand them by removing the parentheses, follow the distributive property and combine like terms:

1. A+(b+c-d)-(c-f) = A + b + c - d - c + f (Remove parentheses) = A + b + f - d (Combine like terms)

2. a+(-b-c)-(-d-c-f) = a - b - c + d + c + f (Remove parentheses) = a + d + f (Combine like terms)

3. a-(-b+c)-(d+c-f) = a + b - c - d - c + f (Remove parentheses) = a + b - 2c + f (Combine like terms)

4. a+(b-c-d)+(c+f) = a + b - c - d + c + f (Remove parentheses) = a + b - d + f (Combine like terms)

5. a+(b+c)+(d-c-f) = a + b + c + d - c - f (Remove parentheses) = a + b + d - f (Combine like terms)

6. a+(b+c)-(c-f) = a + b + c - c + f (Remove parentheses) = a + b + f (Combine like terms)

So, the simplified expressions are as follows:

1. A+(b+c-d)-(c-f) = A + b + f - d
2. a+(-b-c)-(-d-c-f) = a + d + f
3. a-(-b+c)-(d+c-f) = a + b - 2c + f
4. a+(b-c-d)+(c+f) = a + b - d + f
5. a+(b+c)+(d-c-f) = a + b + d - f
6. a+(b+c)-(c-f) = a + b + f
