Answer 2

Let's break down and simplify the given expression step by step:

Expression: (a - b / a^2 + ab - a + b / a^2 - ab) : b / a^2 - b^2

Step 1: Simplify the expression inside the first set of parentheses. (a - b / a^2 + ab - a + b / a^2 - ab) = (a - b) / (a^2 + ab - a + b) / (a^2 - ab) = (a - b) / (a(a - 1) + b(a - 1)) / (a(a + b) - b(a + b)) = (a - b) / (a - 1)(a + b) / (a - b)(a + b) = 1 / (a - 1)

Step 2: Simplify the entire expression using the result from step 1. 1 / (a - 1) : b / (a^2 - b^2) = 1 / (a - 1) * (a^2 - b^2) / b = (a^2 - b^2) / (b(a - 1)) = (a + b)(a - b) / b(a - 1)

So, the simplified expression is: (a + b)(a - b) / b(a - 1)
