2 + x + -1x + x2 = 2(x + -1) + (x2 + -1x)

Combine like terms: x + -1x = 0
2 + 0 + x2 = 2(x + -1) + (x2 + -1x)
2 + x2 = 2(x + -1) + (x2 + -1x)

Reorder the terms:
2 + x2 = 2(-1 + x) + (x2 + -1x)
2 + x2 = (-1 * 2 + x * 2) + (x2 + -1x)
2 + x2 = (-2 + 2x) + (x2 + -1x)

Reorder the terms:
2 + x2 = -2 + 2x + (-1x + x2)

Remove parenthesis around (-1x + x2)
2 + x2 = -2 + 2x + -1x + x2
