Qual o resultado da subtração dos dois polinômios abaixo? (2x2 + 4x) (–2x2 + x – 6)

Len [333]

Answer:

-4x^4-6x^3-8x^2-24x

Step-by-step explanation:

$\left(2x^2+4x\right)\left(-2x^2+x-6\right)\\$

distribuir parênteses

$=2x^2\left(-2x^2\right)+2x^2x+2x^2\left(-6\right)+4x\left(-2x^2\right)+4xx+4x\left(-6\right)$

Aplicar regras de menos mais ; $+\left(-a\right)=-a$

$=-2\times\:2x^2x^2+2x^2x-2\times\:6x^2-4\times\:2x^2x+4xx-4\times\:6x$

simplificar

$-2\times\:2x^2x^2+2x^2x-2\times\:6x^2-4\times\:2x^2x+4xx-4\times\:6x:\\\quad -4x^4-6x^3-8x^2-24x$
