Question

AJUDA PLEASEEEEEE!!!!!!
(x³ + 2x + 4) . (x² - x)

Answer 1

Explicação passo-a-passo:

(x³ + 2x + 4).(x² - x)

= x⁵ + 2x³ + 4x² - x⁴ - 2x² - 4x

= x⁵ - x⁴ + 2x³ + 4x² - 2x² - 4x

= x⁵ - x⁴ + 2x³ + 2x² - 4x

Answer 2

Oie, Td Bom?!

$= (x {}^{3} + 2x + 4) \: . \: (x {}^{2} - x)$

$= x {}^{3} \: . \: (x {}^{2} - x) + 2x \: . \: (x {}^{2} - x) + 4(x {}^{2} - x)$

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

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