Answer 1

Resposta:

$\text{\sf Leia abaixo}$

Explicação passo-a-passo:

$\sf(x + 5).(x + 2)$

$\sf x^2 + 2x + 5x + 10$

$\boxed{\boxed{\sf x^2 + 7x + 10}}$

$\sf(8x^5 - 6x^4) \div (2x)$

$\sf \dfrac{8x^5 - 6x^4}{2x}$

$\boxed{\boxed{\sf 4x^4 - 3x^3}}$

Answer 2

Oie, Td Bom?!

a)

$= (x + 5) \: . \: (x + 2)$

$= x \: . \: (x + 2) + 5(x + 2)$

$= x {}^{2} + 2x + 5x + 10$

$= x {}^{2} + 7x + 10$

b)

$= (8x {}^{5} - 6x {}^{4} ) \div (2x)$

$= \frac{8x {}^{5} - 6x {}^{4} }{2x}$

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

$= 4x {}^{4} - 3x {}^{3}$
