2(x - 1) - (2x - 1)(x + 2)
First, distribute the -1 in the second term:2(x - 1) - (2x - 1)(x + 2) = 2(x - 1) - (2x^2 + 3x - 2)
Next, distribute the 2 in the first term:2x - 2 - 2x^2 - 3x + 2
Combine like terms:-2x^2 - x
Therefore, 2(x - 1) - (2x - 1)(x + 2) simplifies to -2x^2 - x.
2(x - 1) - (2x - 1)(x + 2)
First, distribute the -1 in the second term:
2(x - 1) - (2x - 1)(x + 2) = 2(x - 1) - (2x^2 + 3x - 2)
Next, distribute the 2 in the first term:
2x - 2 - 2x^2 - 3x + 2
Combine like terms:
-2x^2 - x
Therefore, 2(x - 1) - (2x - 1)(x + 2) simplifies to -2x^2 - x.
