2x . (x – 1/7) = 0

=> \(\left[ \begin{array}{l}2x = 0\\x – \dfrac{1}{7} = 0\end{array} \right.\)

=> \(\left[ \begin{array}{l}x=0\\x=\dfrac{1}{7}\end{array} \right.\)

Vậy x ∈ {0 ; 1/7}

2x(x-1/7)=0

\(⇒\left[ \begin{array}{l}2x=0\\x-\dfrac{1}7=0\end{array} \right.\)

\(⇒\left[ \begin{array}{l}x=0\\x=\dfrac{1}7\end{array} \right.\)

Vậy x={0;1/7}
