Step-by-step explanation:

Answer 2

Step-by-step explanation:

$(2p + 3)(2p - 4)(2p - 5) \\ \\ = (2p(2p - 4) + 3(2p - 4))(2p - 5) \\ \\ = (4 {p}^{2} - 8p + 6p - 12)(2p - 5) \\ \\ = (4 {p}^{2} - 2p - 12)(2p - 5) \\ \\ = 4 {p}^{2} (2p - 5) - 2p(2p - 5) - 12(2p - 5) \\ \\ = 8 {p}^{3} - 20 {p}^{2} - 4 {p}^{2} + 10p - 24p + 60 \\ \\ = 8 {p}^{3} - 24 {p}^{2} - 14p + 60$
