\(\left(3x-\frac{1}{2}\right)\left(-\frac{2}{3x+1}\right)=0\)
Để là như vầy hả
\(\left(3x-\frac{1}{2}\right).\left(-\frac{2}{3x+1}\right)=0\)
\(\Rightarrow\frac{6x-1}{2}.\left(-\frac{2}{3x-1}\right)=0\)
\(\Rightarrow\frac{1-6x}{3x-1}=0\Rightarrow1-6x=0\Rightarrow6x=1\Rightarrow x=\frac{1}{6}\)
Vậy x = 1/6
