Answer 2

$\displaystyle\bf\\3(4x-1)^{2}-(4x-1)=0\\\\(4x-1)\cdot\Big[(3\cdot(4x-1)-1\Big]=0\\\\(4x-1)\cdot(12x-3-1)=0\\\\(4x-1)(12x-4)=0\\\\\\\left[\begin{array}{ccc}4x-1=0\\12x-4=0\end{array}\right\\\\\\\left[\begin{array}{ccc}4x=1\\12x=4\end{array}\right\\\\\\\left[\begin{array}{ccc}x_{1} =0,25\\x_{2} =\dfrac{1}{3} \end{array}\right\\\\\\Otvet \ : \ 0,25 \ ; \ \frac{1}{3}$
