give me thank my all answer plz

Answer 2

${\huge{\underbrace{\rm{Answer\checkmark}}}}$

$\mapsto \rm \: (8 {x}^{4} - 3 {x}^{2} + 9x - 8) \times (2 {x}^{2} - 5x + 3)$

$\mapsto \rm \: (8 {x}^{4} - 3 {x}^{2} + 9x - 8)2 {x}^{2} + \\ \rm \: \: (8 {x}^{4} - 3 {x}^{2} + 9x - 8) \times ( - 5x) \\ \rm \: \: (8 {x}^{4} - 3 {x}^{2} + 9x - 8) \times 3$

$\mapsto \rm \: (16 {x}^{6} - 6 {x}^{4} + 18 {x}^{3} - 16 {x}^{2} ) + \\ \rm \: \: \: \: \: \: ( - 40 {x}^{5} + 15 {x}^{3} - 45 {x}^{2} + 40x) + \\ \rm \: \: \: \: \: \: (24 {x}^{4} - 9 {x}^{2} + 27x - 24)$

$\mapsto \rm \: 16 {x}^{6} - 6 {x}^{4} + 18 {x}^{3} - 16 {x}^{2} - 40 {x}^{5} + 15 {x}^{3} \\ \rm \: \: - 45 {x}^{2} + 40x + 24 {x}^{4} - 9 {x}^{2} + 27x - 24$

$\mapsto \boxed{\rm \: 16 {x}^{6} - 40 {x}^{5} + 18 {x}^{4} + 33 {x}^{3} - 70 {x}^{2} + 67x - 24}$
