Answer 2

Step-by-step explanation:

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

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

$= {4x}^{3} - {12x}^{2} + 20x + {3x}^{2 } - 9x + 15 - (( {4x}^{3} + 6 {x}^{2} - 10x - {6x}^{2} - 9x + 15)$

.

$= 4 {x}^{3} - 9 {x}^{2} + 11x + 15 - ({4x}^{3} - 19x - 5)$

$= {4x}^{3} - 9 {x}^{2} +11x + 15 - {4x}^{3} + 19x + 5 = 0$

$\mapsto$

$- {9x}^{2} + 30x + 20 =$

${9x}^{2} - 30x - 20 = 0$
