1] (a - 3) (a² - 2a + 5) = a³ - 2a² + 5a - 3a² + 6a - 15 = a³ - 5a² + 11a - 15

2] (2x - 3) (4x² + 6x + 9) = 8x³ + 12x² + 18x - 12x² - 18x - 27 = 8x³ - 27

3] (4x + 2) (16x² - 8x + 4) = 64x³ - 32x² + 16x + 32x² - 16x + 8 = 64x³ + 8

4] (2p + q) (p² + pq + q²) = 2p³ + 2p²q + 2pq² + p²q + pq² + q³ = 2p³ + 3p²q + 3pq² + q³
