(a raise to 2x - root2a raise to 2x + 1) (a raise to 2x + root2a raise to 2x + 1)

You have the expression:

\[
\left( a^{2x} - \sqrt{2} a^{2x} + 1 \right) \left( a^{2x} + \sqrt{2} a^{2x} + 1 \right)
\]

This is a product of two binomial expressions. We can simplify it by using the distributive property (or FOIL method: First, Outside, Inside, Last). Let's expand it:

### Step-by-step Expansion:

1. **First terms**: Multiply the first terms of both binomials:
   \[
   a^{2x} \cdot a^{2x} = (a^{2x})^2 = a^{4x}
   \]

2. **Outside terms**: Multiply the outside terms:
   \[
   a^{2x} \cdot \sqrt{2} a^{2x} = \sqrt{2} (a^{2x})^2 = \sqrt{2} a^{4x}
   \]

3. **Inside terms**: Multiply the inside terms:
   \[
   - \sqrt{2} a^{2x} \cdot a^{2x} = - \sqrt{2} (a^{2x})^2 = - \sqrt{2} a^{4x}
   \]

4. **Last terms**: Multiply the last terms:
   \[
   (- \sqrt{2} a^{2x}) \cdot (\sqrt{2} a^{2x}) = -(\sqrt{2})^2 a^{4x} = -2 a^{4x}
   \]
   and
   \[
   1 \cdot 1 = 1
   \]

### Combining the terms:

Now add all the terms together:
\[
a^{4x} + \sqrt{2} a^{4x} - \sqrt{2} a^{4x} - 2 a^{4x} + 1
\]

Notice that \(\sqrt{2} a^{4x}\) and \(- \sqrt{2} a^{4x}\) cancel each other out, so we are left with:

\[
a^{4x} - 2 a^{4x} + 1
\]

This simplifies to:

\[
- a^{4x} + 1
\]

Thus, the simplified form of the given expression is:

\[
1 - a^{4x}
\]
