1 + 2x + x2 + -1(-1 + x)(-1 + x) = x + 9

Multiply (-1 + x) * (-1 + x)
1 + 2x + x2 + -1(-1(-1 + x) + x(-1 + x)) = x + 9
1 + 2x + x2 + -1((-1 * -1 + x * -1) + x(-1 + x)) = x + 9
1 + 2x + x2 + -1((1 + -1x) + x(-1 + x)) = x + 9
1 + 2x + x2 + -1(1 + -1x + (-1 * x + x * x)) = x + 9
1 + 2x + x2 + -1(1 + -1x + (-1x + x2)) = x + 9

1 + 2x + x2 + -1(1 + -2x + x2) = x + 9
1 + 2x + x2 + (1 * -1 + -2x * -1 + x2 * -1) = x + 9
1 + 2x + x2 + (-1 + 2x + -1x2) = x + 9

Reorder the terms:
1 + -1 + 2x + 2x + x2 + -1x2 = x + 9

Combine like terms: 1 + -1 = 0
0 + 2x + 2x + x2 + -1x2 = x + 9
2x + 2x + x2 + -1x2 = x + 9

Combine like terms: 2x + 2x = 4x
4x + x2 + -1x2 = x + 9

Combine like terms: x2 + -1x2 = 0
