(2x - y)(4x² + 2xy + y²)

To multiply the given expression, we can use the distributive property.

(2x - y)(4x² + 2xy + y²) = 2x(4x²) + 2x(2xy) + 2x(y²) - y(4x²) - y(2xy) - y(y²)

Simplifying each term:

= 8x³ + 4x²y + 2xy² - 4x²y - 2xy² - y³

Combining like terms, we can combine the middle terms:

= 8x³ - 4x²y - 2xy² - y³
