Question

ME AJUDEM, POR FAVOR!!!!!!!!!!!!!! A) ( 6x^4-10x^3+9x^2+9x-5) × ( 2x^2)

Answer 1

Explicação passo-a-passo:

Temos que:

(6x⁴ - 10x³ + 9x² + 9x - 5) . 2x² = 12x⁶ - 20x⁵ + 18x⁴ + 18x³ - 10x²

Answer 2

Oie, Td Bom?!

$= (6x {}^{4} - 10x {}^{3} + 9x {}^{2} + 9x - 5) \: . \: (2x {}^{2} )$

$= (6x {}^{4} - 10x {}^{3} + 9x {}^{2} + 9x - 5) \: . \: 2x {}^{2}$

$= 6x {}^{4} \: . \: 2x {}^{2} - 10x {}^{3} \: . \: 2x {}^{2} + 9x {}^{2} \: . \: 2x {}^{2} + 9x \: . \: 2x {}^{2} - 5 \: . \: 2x {}^{2}$

$= 12x {}^{6} - 20x {}^{5} + 18x {}^{4} + 18x {}^{3} - 10x {}^{2}$
