Answer:
6 ( x + 2y )³ - 8 ( x + 2y )² + 4 ( x + 2y )
= 6{ x³ + 3x²2y + 3x(2y)² + (2y)³} - 8 { x² + 2x2y + (2y)² + 4 ( x + 2y )
= 6 (x³ + 6x²y + 12xy² + 8y³ ) - 8 ( x² + 4xy + 4y² ) + 4 ( x + 2y )
= (6x³ + 36x²y + 72xy² + 48y³) - (8x² + 32xy + 32y² ) + (4x + 8y)
= 6x³ + 36x²y + 72xy² + 48y³ - 8x² - 32xy - 32y² + 4x + 8y
