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

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

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

Multiply (-1 + 2x) * (3 + x)
Y = 3x(-1(3 + x) + 2x * (3 + x))
Y = 3x((3 * -1 + x * -1) + 2x * (3 + x))
Y = 3x((-3 + -1x) + 2x * (3 + x))
Y = 3x(-3 + -1x + (3 * 2x + x * 2x))
Y = 3x(-3 + -1x + (6x + 2x2))

Combine like terms: -1x + 6x = 5x
Y = 3x(-3 + 5x + 2x2)
Y = (-3 * 3x + 5x * 3x + 2x2 * 3x)
