Answer 2

To simplify the expression X(x - 1) * 2 - (3 - x) * (x + 1), we'll first perform the operations within the parentheses and then combine like terms:

1. Distribute the terms inside the second set of parentheses: X(x - 1) * 2 - (3 - x) * (x + 1) = X(x2 - 12) - (3x + 3(-1)) = 2X(x - 2) - (3x - 3)

2. Distribute the X: = 2X * x - 2X * 2 - 3x + 3

3. Combine like terms: = (2X - 3)x - 4 + 3 = (2X - 3)x - 1

So the simplified expression is: (2X - 3)x - 1
