Simplifying
x(2x + -4) = (2x + 8)(x + -3)

Reorder the terms:
x(-4 + 2x) = (2x + 8)(x + -3)
(-4 * x + 2x * x) = (2x + 8)(x + -3)
(-4x + 2x2) = (2x + 8)(x + -3)

Reorder the terms:
-4x + 2x2 = (8 + 2x)(x + -3)

Reorder the terms:
-4x + 2x2 = (8 + 2x)(-3 + x)

Multiply (8 + 2x) * (-3 + x)
-4x + 2x2 = (8(-3 + x) + 2x * (-3 + x))
-4x + 2x2 = ((-3 * 8 + x * 8) + 2x * (-3 + x))
-4x + 2x2 = ((-24 + 8x) + 2x * (-3 + x))
-4x + 2x2 = (-24 + 8x + (-3 * 2x + x * 2x))
-4x + 2x2 = (-24 + 8x + (-6x + 2x2))

Combine like terms: 8x + -6x = 2x
-4x + 2x2 = (-24 + 2x + 2x2)
