1)

Fill in the proof to simplify: (2x -1 + x² -2x + 1) - 2x + 1:

Statement	Reason
(2x -1 + x² -2x + 1) - 2x + 1
(x² -2x + 1 + 2x -1) - 2x + 1
x² -2x + 1 + (2x -1 - 2x + 1)
x² -2x + 1 + 0
x² -2x + 1

2)

Fill in the proof to simplify: 2(-3x² + x + 4) + 4(-3x² + x + 4):

Statement	Reason
2(-3x² + x + 4) + 4(-3x² + x + 4)
(2 + 4)(-3x² + x + 4)
(6)(-3x² + x + 4)
-18x² + 6x + 24

3)

Fill in the proof to simplify: -4(-4x² + 4x -4) - 5(-4x² + 4x -4):

Statement	Reason
-4(-4x² + 4x -4) - 5(-4x² + 4x -4)
(-4 - 5)(-4x² + 4x -4)
(-9)(-4x² + 4x -4)
36x² -36x + 36

4)

Fill in the proof to simplify: (-4 + x² + x + 1) + 4:

Statement	Reason
(-4 + x² + x + 1) + 4
(x² + x + 1 - 4) + 4
x² + x + 1 + (-4 + 4)
x² + x + 1 + 0
x² + x + 1
