Simplifying
(x + -2)(x + 1)(4 + -1x) = 0

Reorder the terms:
(-2 + x)(x + 1)(4 + -1x) = 0

Reorder the terms:
(-2 + x)(1 + x)(4 + -1x) = 0

Multiply (-2 + x) * (1 + x)
(-2(1 + x) + x(1 + x))(4 + -1x) = 0
((1 * -2 + x * -2) + x(1 + x))(4 + -1x) = 0
((-2 + -2x) + x(1 + x))(4 + -1x) = 0
(-2 + -2x + (1 * x + x * x))(4 + -1x) = 0
(-2 + -2x + (1x + x2))(4 + -1x) = 0

Combine like terms: -2x + 1x = -1x
(-2 + -1x + x2)(4 + -1x) = 0

Multiply (-2 + -1x + x2) * (4 + -1x)
(-2(4 + -1x) + -1x * (4 + -1x) + x2(4 + -1x)) = 0
((4 * -2 + -1x * -2) + -1x * (4 + -1x) + x2(4 + -1x)) = 0
((-8 + 2x) + -1x * (4 + -1x) + x2(4 + -1x)) = 0
(-8 + 2x + (4 * -1x + -1x * -1x) + x2(4 + -1x)) = 0
(-8 + 2x + (-4x + 1x2) + x2(4 + -1x)) = 0
(-8 + 2x + -4x + 1x2 + (4 * x2 + -1x * x2)) = 0
(-8 + 2x + -4x + 1x2 + (4x2 + -1x3)) = 0

Combine like terms: 2x + -4x = -2x
(-8 + -2x + 1x2 + 4x2 + -1x3) = 0
