SUMMARY
The integral ∫x³e^(x²)dx cannot be solved using elementary functions, as confirmed in the discussion. The correct approach involves using substitution effectively, particularly the substitution method applied earlier in the problem. The final solution is expressed as (e^(x²)x²/2) - (1/2)e^(x²) + C. Participants emphasized the importance of recognizing when to avoid integrating e^(x²) directly due to its complexity.
