Simplifying the polynomial gives:

(x² + 3x + 9)/(x³ + 6x² + 18x + 27)

How to carry out polynomial division?

(x³ - 27) ÷ (x⁴ + 3x³ - 27x - 81)

Factoring (x³ - 27) gives us:

(x - 3)(x² + 3x + 9)

Factorizing (x⁴ + 3x³ - 27x - 81) gives:

(x - 3)(x³ + 6x² + 18x + 27)

Thus:

(x³ - 27) ÷ (x⁴ + 3x³ - 27x - 81) = [(x - 3)(x² + 3x + 9)]/[(x - 3)(x³ + 6x² + 18x + 27)]

= (x² + 3x + 9)/(x³ + 6x² + 18x + 27)
