SUMMARY
The integral of the function sqrt(1 + x^4 + 2x^2) simplifies to (1 + x^2) after recognizing that 1 + x^4 + 2x^2 can be expressed as (1 + x^2)^2. The discussion emphasizes the importance of substitution, specifically letting x^2 = u, to facilitate the integration process. Ultimately, the integral simplifies to finding the integral of (1 + x^2)dx, which is straightforward.
