Simplifying
8 + -8x = (3x + 1)(x + -1)

Reorder the terms:
8 + -8x = (1 + 3x)(x + -1)

Reorder the terms:
8 + -8x = (1 + 3x)(-1 + x)

Multiply (1 + 3x) * (-1 + x)
8 + -8x = (1(-1 + x) + 3x * (-1 + x))
8 + -8x = ((-1 * 1 + x * 1) + 3x * (-1 + x))
8 + -8x = ((-1 + 1x) + 3x * (-1 + x))
8 + -8x = (-1 + 1x + (-1 * 3x + x * 3x))
8 + -8x = (-1 + 1x + (-3x + 3x2))

Combine like terms: 1x + -3x = -2x
8 + -8x = (-1 + -2x + 3x2)

Solving
8 + -8x = -1 + -2x + 3x2

Solving for variable 'x'.
