5x²-3x + 2x³-4
resposta urgente ​

Answer 1

Resposta:

$\sf{5x²-3x + 2x³-4}$

$\sf{2 {x}^{2} + 5 {x}^{2} - 3x - 4 }$

$\sf{2 {x}^{3} - 2x {}^{2} + 7 {x}^{2} - 3x - 4 }$

$\sf{2 {x}^{3} - 2 {x}^{2} + 7 {x}^{2} - 7x + 4x - 4 }$

$\sf{2 {x}^{2} .(x - 1) + 7 {x}^{2} - 7x + 4x - 4}$

$\sf{2 {x}^{2} .(x - 1) + 7x.(x - 1) + 4x - 4}$

$\sf{2 {x}^{2}.(x - 1) + 7x.(x - 1) + 4(x - 1) }$

$\rightarrow\boxed{\boxed{\sf{(x - 1)x(2x {}^{2} + 7x + 4) }}}\checkmark$
