Simplifying
3 + -3x = (2x + 3)(x + -1)

Reorder the terms:
3 + -3x = (3 + 2x)(x + -1)

Reorder the terms:
3 + -3x = (3 + 2x)(-1 + x)

Multiply (3 + 2x) * (-1 + x)
3 + -3x = (3(-1 + x) + 2x * (-1 + x))
3 + -3x = ((-1 * 3 + x * 3) + 2x * (-1 + x))
3 + -3x = ((-3 + 3x) + 2x * (-1 + x))
3 + -3x = (-3 + 3x + (-1 * 2x + x * 2x))
3 + -3x = (-3 + 3x + (-2x + 2x2))
