\(3\left(2x-1\right)\left(3x-1\right)-\left(2x-3\right)\left(9x-1\right)=0\)
\(\Rightarrow3\left(6x^2-2x-3x+1\right)-\left(18x^2-2x-27x+3\right)=0\)
\(\Rightarrow18x^2-6x-9x+3-18x^2+2x+27x-3=0\)
\(\Rightarrow\left(18x^2-18x^2\right)+\left(-6x-9x+2x+27x\right)=-3+3\)
\(\Rightarrow14x=0\Rightarrow x=0\)
Vậy \(x=0\)
Chúc bạn học tốt!!!
