Answer 2

To simplify the given expression, let's combine like terms:

Expression: x^3 - 3x^2 + 3x - 1 - x^2 + 19

Step 1: Group the terms with the same power of x. (x^3) + (-3x^2 - x^2) + (3x) + (-1 + 19)

Step 2: Combine like terms within each group. x^3 + (-4x^2) + 3x + 18

The simplified expression is: x^3 - 4x^2 + 3x + 18
