Integral 1 + x square by( 3 - 4 root 2 into x + 4 x power 4)

To solve the integral of the expression \( \frac{1 + x^2}{3 - 4\sqrt{2}x + 4x^4} \), we'll first rewrite it in a more standard mathematical notation:

\[
\int \frac{1 + x^2}{3 - 4\sqrt{2}x + 4x^4} \, dx
\]

This integral can be quite complex, so let's approach it step by step.

### Step 1: Factor the Denominator
The denominator \( 3 - 4\sqrt{2}x + 4x^4 \) may be factored to simplify the expression, or we may need to use partial fraction decomposition if the factorization is possible.

However, in this case, the denominator is not easily factorizable into simpler polynomials, so we'll consider other integration techniques such as substitution.

### Step 2: Consider Substitution
Let's use a substitution to simplify the integrand. One possible substitution is \( u = x^2 \). Therefore, \( du = 2x \, dx \). We need to rewrite the integrand in terms of \( u \).

However, this method does not simplify the problem significantly, so we may consider numerical or computer algebra systems for an exact answer.

### Step 3: Numerical Integration or Advanced Techniques
Given the complexity of the denominator, the integral may not have a simple closed-form solution. We might either:
- Use advanced methods like hyperbolic substitution or trigonometric substitution, which can be quite involved.
- Evaluate the integral numerically if an exact expression is not required.

### Step 4: Final Solution
Without further simplification techniques working effectively here, the integral is best approached through numerical methods or considered as an advanced case, possibly involving elliptic integrals or special functions.
