Answer 1

Respuesta:

$= 16 {x}^{9} - 72 {x}^{8} + 204 {x}^{7} - 342 {x}^{6} + 408 {x}^{5} - 288 {x}^{4} + 138 {x}^{3} - 15 {x}^{2} + 20x - 3$

Explicación paso a paso:

$p = 2 {x}^{3} + 5x - 3 + .q(x).16 {x}^{9} - 72 {x}^{8} + 204 {x}^{7} - 342 {x}^{6} + 408 {x}^{5} - 288 {x}^{4} + 138 {x}^{3} - 15 {x}^{2} + 20x - 3$

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

Expandir

$2(4x - 3 {x}^{2} + 2 {x}^{3} )^{3} + 5(4x - 3 {x}^{2} + 2 {x}^{3} - 3 \: \: \: \: \: 16 {x}^{9} - 72 {x}^{8} + 204 {x}^{7} - 342 {x}^{6} + 408 {x}^{5} - 288 {x}^{4} + 138 {x}^{3} + 138 {x}^{3} - 15 {x}^{2} - 20x - 3$

R=

$16 {x}^{9} - 72 {x}^{8} - 204 {x}^{7} - 342 {x}^{6} + 408 {x}^{5} - 288 {x}^{4} + 288 {x}^{4} - 138 {x}^{3} - 15 {x}^{2} + 20x - 3$
