Answer:
36x²y - 54xy² + 27y³
Step-by-step explanation:
8x³ - (2x - 3y)³
(a - b)³ = a³ - 3a²b + 3ab² - b³
8x³ - (2x³- 3× 2x² × 3y + 3 × 2x × 3y² - 3y³)
8x³ - (8x³ - 3 × 4x² × 3y + 3× 2x × 9y² - 27y³)
8x³ - (8x³ - 36x²y + 54xy² - 27y³)
8x³ - ( - 8x³ + 36x²y - 54xy² + 27y³)
8x³ and -8x³ will cut
36x²y - 54xy² + 27y³
