Answer 2

To simplify the expression, let's break it down step by step:

1. Simplify the denominator: We have 1\a - b - 1\a + b in the denominator. Notice that the terms 1\a and -1\a will cancel each other out. Similarly, the terms -b and b will also cancel each other out. Therefore, the denominator simplifies to 0.

2. Rewrite the expression: After simplifying the denominator to 0, we're left with the expression: 2a + 2b\b • (0)

3. Further simplification: Any expression multiplied by 0 is equal to 0. Therefore, the entire expression simplifies to 0.

So, the simplified expression is 0.
