Answer 2

Step-by-step explanation:

$( {6x}^{2} + 5x - 1)(4 - {2x}^{3} - {4x}^{2} )$

${24x}^{2} - {12x}^{5} - {24x}^{4} + 20x - {10x}^{4} - {20x}^{3} - 4 + {2x}^{3} + {4x}^{2}$

Arrange all the terms...

$- {12x}^{5} - {24x}^{4} - {10x}^{4} - {20x}^{3} + {2x}^{3} + {24x}^{2} + {4x}^{2} + 20x - 4$

$- 12 {x}^{5} - 34 {x}^{4} - 18 {x}^{3} + 28 {x}^{2} - 20x - 4$

$= > - 6 {x}^{5} - 17 {x}^{4} - 9 {x}^{3} + 14 {x}^{2} - 10x - 2$
