x(-3 + 3x) + x(6x + -2) = (9x + 8)(x + -1)
(-3 * x + 3x * x) + x(6x + -2) = (9x + 8)(x + -1)
(-3x + 3x2) + x(6x + -2) = (9x + 8)(x + -1)

Reorder the terms:
-3x + 3x2 + x(-2 + 6x) = (9x + 8)(x + -1)
-3x + 3x2 + (-2 * x + 6x * x) = (9x + 8)(x + -1)
-3x + 3x2 + (-2x + 6x2) = (9x + 8)(x + -1)

Reorder the terms:
-3x + -2x + 3x2 + 6x2 = (9x + 8)(x + -1)

Combine like terms: -3x + -2x = -5x
-5x + 3x2 + 6x2 = (9x + 8)(x + -1)

Combine like terms: 3x2 + 6x2 = 9x2
-5x + 9x2 = (9x + 8)(x + -1)

Reorder the terms:
-5x + 9x2 = (8 + 9x)(x + -1)

Reorder the terms:
-5x + 9x2 = (8 + 9x)(-1 + x)

Multiply (8 + 9x) * (-1 + x)
-5x + 9x2 = (8(-1 + x) + 9x * (-1 + x))
-5x + 9x2 = ((-1 * 8 + x * 8) + 9x * (-1 + x))
-5x + 9x2 = ((-8 + 8x) + 9x * (-1 + x))
-5x + 9x2 = (-8 + 8x + (-1 * 9x + x * 9x))
-5x + 9x2 = (-8 + 8x + (-9x + 9x2))

Combine like terms: 8x + -9x = -1x
-5x + 9x2 = (-8 + -1x + 9x2)

Add '-9x2' to each side of the equation.
-5x + 9x2 + -9x2 = -8 + -1x + 9x2 + -9x2
