This can be simplified by combining like terms:
X²(x-3) - 2x(x-3) + (x-3)= x²x - 3x² - 2x² + 6x + x - 3= x³ - 3x² - 2x² + 6x + x - 3= x³ - 5x² + 7x - 3
Therefore, the simplified expression is x³ - 5x² + 7x - 3.
This can be simplified by combining like terms:
X²(x-3) - 2x(x-3) + (x-3)
= x²x - 3x² - 2x² + 6x + x - 3
= x³ - 3x² - 2x² + 6x + x - 3
= x³ - 5x² + 7x - 3
Therefore, the simplified expression is x³ - 5x² + 7x - 3.
