Answer 2

It seems like you've provided a mathematical expression, but it's a bit unclear due to the formatting. Let's break down the expression step by step to ensure we understand it correctly:

The given expression is:

(5a / (a - 1)) - (a^2) + (a / 6) * (18 / (a + 1))

Let's simplify this step by step:

1. Simplify the fractions:

   • 5a / (a - 1)
   • a / 6
   • 18 / (a + 1)

2. Multiply a / 6 by 18 / (a + 1)

3. Subtract a^2 from the result of the previous step
