Đáp án:
$\cdot$
Giải thích các bước giải:
$\left(\sqrt{x-1}-5\right)\!.\!\left(x-6\sqrt x\right)=0\\\Rightarrow \left\{\begin{matrix}\sqrt{x-1}-5=0\\x-6\sqrt x=0\end{matrix}\right.\\\Rightarrow \sqrt{x-1}=5\\\Rightarrow \sqrt{x-1}=\sqrt{25}\\\Rightarrow x-1=25\Rightarrow x=26\\\Rightarrow x-6\sqrt x=0\\\Rightarrow x=6\sqrt x\\\Rightarrow\sqrt{x^2}=\sqrt{36x}\\\Rightarrow x^2=36x\\\Rightarrow\left\{\begin{matrix}x=0\\x=26\\x=36\end{matrix}\right.$
