Me ajuda

Answer 1

Resposta:

$\\=4x^2\left(x-4\right)\left(x+6\right)ou =4x^4+8x^3-96x^2$

Explicação passo-a-passo:

$\left(x-4\right)x\cdot \:2x\cdot \:2\left(x+6\right)=\\\\\mathrm{Multiplicar\:os\:numeros:}\:2\cdot \:2=4\\=4xx\left(x-4\right)\left(x+6\right)\\\\\mathrm{Aplicar\:as\:propriedades\:dos\:expoentes}:\quad \:a^b\cdot \:a^c=a^{b+c}\\xx=\:x^{1+1}\\\\4\left(x-4\right)x^{1+1}\left(x+6\right)= \\\\\mathrm{Somar:}\:1+1=2\\\\=4\left(x-4\right)x^2\left(x+6\right)$

$\\=4x^2\left(x-4\right)\left(x+6\right)\\=4x^4+8x^3-96x^2$
