Answer 2

Let's simplify the expression step by step:

1. Start by simplifying the innermost parentheses: -5/11(7 - 5/11) - (-5/11 - 2)^2

2. Inside the parentheses, we can perform subtraction: -5/11(6 6/11) - (-7/11)^2

3. Now, convert the mixed number 6 6/11 to an improper fraction: -5/11(72/11) - (-7/11)^2

4. Next, multiply -5/11 by 72/11: -360/121 - (-7/11)^2

5. To square -7/11, multiply it by itself: -360/121 - (49/121)

6. Subtract the second term from the first term: -360/121 - 49/121

7. Combine the fractions by keeping a common denominator (121): (-360 - 49) / 121

8. Perform the subtraction: -409 / 121

So, the simplified expression is -409/121.
