Answer 2

Let's simplify the expression step by step:

1. Factor out the common term (a+5) from the first and fifth terms: (a+5)6a(1-5a)/(1-5a)(a+1)a(a+5) + a^2 + 5/(a+1)

2. Cancel out (1-5a) from the second and fourth terms: (a+5)6a(a+1)a(a+5) + a^2 + 5/(a+1)

3. Multiply the terms in the first part: 6a*(a+1)a(a+5)*(a+5) + a^2 + 5/(a+1)

4. Expand (a+1) * a * (a+5) * (a+5): 6a*(a^2 + 6a + 5)*(a+5) + a^2 + 5/(a+1)

5. Multiply 6a with the terms inside the parentheses: 6a*(a^3 + 11a^2 + 30a + 25) + a^2 + 5/(a+1)

6. Distribute 6a to all the terms inside the parentheses: 6a^4 + 66a^3 + 180a^2 + 150a + a^2 + 5/(a+1)

7. Combine like terms: 6a^4 + 66a^3 + 181a^2 + 150a + 5/(a+1)

So, the simplified expression is: 6a^4 + 66a^3 + 181a^2 + 150a + 5/(a+1)
