SUMMARY
The discussion centers on the polynomial long division of the expression $$\frac{x^3 + 4x^2 + 3}{x+4}$$. The correct result of this division is $$x^2 + \frac{3}{x+4}$$, which was miscalculated by the user as $$x^2 + 1 - \frac{1}{x+4}$$. The error occurred during the subtraction step where the user incorrectly simplified the terms, leading to an inaccurate remainder. The proper execution of polynomial long division reveals that the remainder is 3, not 1.
