Answer 1

Answer:

$\bold{ (2 {x}^{3} - 10 {x}^{2} - 7x - 5)}$

Step-by-step explanation:

$\bold{(3 {x}^{2} + 5x - 7)(x - 1) - ( {x}^{2} - 2x + 3)(x + 4)}\\ \bold{(3 {x}^{3} - 5 {x}^{2} - 7x - 3 {x}^{2} - 5x + 7 - {x}^{3} + 2 {x}^{2} - 3x - 4 {x}^{2} + 8x - 12)} \\ \bold{ (2 {x}^{3} - 10 {x}^{2} - 7x - 5)}$
