Reorder the terms:
x(-3 + x)(x + 4) = 0

Reorder the terms:
x(-3 + x)(4 + x) = 0

Multiply (-3 + x) * (4 + x)
x(-3(4 + x) + x(4 + x)) = 0
x((4 * -3 + x * -3) + x(4 + x)) = 0
x((-12 + -3x) + x(4 + x)) = 0
x(-12 + -3x + (4 * x + x * x)) = 0
x(-12 + -3x + (4x + x2)) = 0

Combine like terms: -3x + 4x = 1x
x(-12 + 1x + x2) = 0
(-12 * x + 1x * x + x2 * x) = 0
(-12x + 1x2 + x3) = 0
