Question

2x-6x(x-9)=4(3-2x) quanto da?

Answer 1

$\begin{matrix} \underbrace{ \ \ Produtos \ \ Not\acute{a}veis \ \ } \\\\ 2x \ - \ 6x \ (x \ - \ 9) \ \ = \ \ 4 \ (3 \ - \ 2x) \\\\ 2x \ - \ 6x^{2} \ + \ 54x \ \ = \ \ 12 \ - \ 8x \\\\ - \ 6x^{2} \ + \ 2x \ + \ 54x \ + \ 8x \ \ = \ \ 12 \\\\ - \ 6x^{2} \ + \ 64x \ \ = \ \ 12 \\\\ \boxed{ \ - \ 6x^{2} \ + \ 64x \ - \ 12 \ \ = \ \ 0 \ } \end{matrix}$

Answer 2

Resposta:

Explicação passo-a-passo:

2X - 6X² + 54X = 12 - 8X

-6x² + 2x + 54x +8x - 12 =0

-6x² +64x -12 = 0
