To factor the polynomial x³ - 9x² + 9x - 81, we can use various factoring methods to simplify the expression. In this case, we'll use the grouping method:

Step 1: Group the terms: (x³ - 9x²) + (9x - 81)

Step 2: Factor out the common factor from each group:
In the first group, we can factor out x²: x²(x - 9).
In the second group, we can factor out 9: ...
