Question

“) A resposta correta de 3x2 - 6x = 0 é:
S={0}
S={2}
S = 0
S={0,2}​

Answer 1

Coloque o x Em evidência:

$\boxed{ \begin{array}{lr} \ \\ \large \sf {3x}^{2} - 6x = 0 \\ \\\large \sf x(3x - 6) = 0 \\ \\ \large \sf \: x =\begin{cases} \large \sf x = 0\\ \large \sf3x - 6\end{cases} \\ \: \end{array}}$

$\large \boxed{ \boxed{ \large \sf \: x_{1} = 0}} \\ \\ \\ \boxed{ \begin{array}{lr} \\ \large \sf \:3x - 6 = 0 \\ \\ \large \sf \:3x = 6 \\ \\ \large \sf \:x = \ \dfrac{6}{3} \\ \\ \boxed{ \red{\large \sf \:x_{2} = 2}} \\ \: \end{array}}$

➡️ Resposta:

$\bullet \: \: \huge \boxed{ \boxed{ \sf S = \{0,2 \}}}$
