Reorder the terms:
(2 + x)(-2 + x)(2x + 4) = 0

Reorder the terms:
(2 + x)(-2 + x)(4 + 2x) = 0

Multiply (2 + x) * (-2 + x)
(2(-2 + x) + x(-2 + x))(4 + 2x) = 0
((-2 * 2 + x * 2) + x(-2 + x))(4 + 2x) = 0
((-4 + 2x) + x(-2 + x))(4 + 2x) = 0
(-4 + 2x + (-2 * x + x * x))(4 + 2x) = 0
(-4 + 2x + (-2x + x2))(4 + 2x) = 0

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