Answer 1

Explicación paso a paso:

$( {9x}^{2} - 9x + 1)(12 {x}^{2} - x - 6) \\ 9 {x}^{2} (12 {x}^{2} ) - 9 {x}^{2} (x) - 9 {x}^{2} (6) - 9x(12 {x}^{2} ) + 9x(x) + 9x(6) + 12 {x}^{2} - x - 6 \\ 108 {x}^{4} - 9 {x}^{3} - 54 {x}^{2} - 108 {x}^{3} + 9 {x}^{2} + 54x + 12 {x}^{2} - x - 6 \\ 108 {x}^{4} - 117 {x}^{3} - 33 {x}^{2} + 53x - 6$
