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

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

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

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

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

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

Add '-1x2' to each side of the equation.
1 + -2x + x2 + -1x2 = -2 + 1x + x2 + -1x2

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

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

Solving
1 + -2x = -2 + 1x

Solving for variable 'x'.
