ĐKXĐ: \(x\ge0\)
\(\Leftrightarrow9\sqrt{x}-15-\left(4\sqrt{x}-14\right)=6x-6\)
\(\Leftrightarrow5\sqrt{x}-1=6x-6\)
\(\Leftrightarrow6x-5\sqrt{x}-5=0\)
\(\Leftrightarrow\left[{}\begin{matrix}\sqrt{x}=\frac{5+\sqrt{145}}{12}\\\sqrt{x}=\frac{5-\sqrt{145}}{12}< 0\left(l\right)\end{matrix}\right.\)
\(\Rightarrow x=\frac{85+5\sqrt{145}}{72}\)
