Question

(2x³- 4x²+5x) x (x - 1)​

Answer 1

Resposta:

$\sf{(2x³- 4x²+5x) x (x - 1)}$

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

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

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

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

$\sf{2 {x}^{4} - 6 {x}^{3} + 4 {x}^{2} + 5 {x}^{2} - 5x}$

$\rightarrow\boxed{\boxed{\sf{2 {x}^{4} - 6 {x}^{3} + 9 {x}^{2} - 5x }}}\checkmark$
