The expression you've provided seems to have formatting issues, but I'll interpret it as best as I can and simplify it. It appears to involve a logarithmic function and some constants or variables. 

It looks like the expression is:

\[ 1 = \left(2u^2 + 8au + 16a^2 \ln|u|\right) - 4a - a \]

Let's simplify this step by step.

### Step 1: Simplify the constants
Combine the constants on the right-hand side:
\[ -4a - a = -5a \]

So the equation becomes:
\[ 1 = 2u^2 + 8au + 16a^2 \ln|u| - 5a \]

### Step 2: Isolate the terms with \( u \)
To isolate the terms involving \( u \), you can write the equation as:
\[ 2u^2 + 8au + 16a^2 \ln|u| = 1 + 5a \]

This equation is simplified but does not have a straightforward solution for \( u \) because of the logarithmic term. Depending on the context, you may need to solve this numerically or explore specific values for \( a \).

Would you like further details or assistance with solving this for specific values of \( u \) or \( a \)? Here are some related questions that could help expand on this:

1. How can we solve the quadratic equation without the logarithmic term?
2. What happens to the equation if we assume \( u \) is very large or very small?
3. Can the equation be solved numerically for a given value of \( a \)?
4. What are the implications of the logarithmic term \( \ln|u| \) in solving for \( u \)?
5. How does the equation change if we set \( a = 0 \)?

**Tip:** When dealing with complex expressions involving logarithms, consider whether a numerical solution or approximation might be more practical than an algebraic one.
