Question

2x (2x² + 3y + 1) – (4x³ + 2x + y²) . estou com dúvida

Answer 1

Resposta:

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

$\sf 4x^3 +6xy + 2x - 4x^3 - 2x -y^2$

$\sf 4x^3 - 4x^3 +6xy + 2x - 2x -y^2$

$\sf 6xy - y^2 = y (6x -y)$

Explicação passo-a-passo:

Answer 2

Oie, Td Bom?!

$= 2x \: . \: (2x {}^{2} + 3y + 1) - (4x {}^{3} + 2x + y {}^{2} )$

$= 4x {}^{3} + 6xy + 2x - 4x {}^{3} - 2x - y {}^{2}$

$= 6xy + 2x - 2x - y {}^{2}$

$= 6xy - y {}^{2}$
