Answer 1

Answer:

$8x(3 {x}^{2} + 5x + 7) + 6(3 {x}^{2} + 5x + 7) = 10x(3 {x}^{2} + 4x + 6) + 14(3 {x}^{2} + 4x + 6) \\ 24 {x}^{3} + 40 {x}^{2} + 56x + 18 {x}^{2} + 30x + 42 = 30 {x}^{3} + 40 {x}^{2} + 60x + 42 {x}^{2} + 56x + 84 \\ 24 {x}^{3} + 58 {x}^{2} + 86x + 42 = 30 {x}^{3} + 82 {x}^{2} + 116x + 84 \\ (24 {x}^{3} - 30 {x}^{3}) + (58 {x}^{2} - 86 {x}^{2} ) + (86x - 116x) = 84 - 42 \\ - 6 {x}^{3} - 28 {x}^{2} - 30x = 42$
