Đáp án: $x=4$

Giải thích các bước giải:

${{x}^{2}}-6x+26=6\sqrt{2x+1}$ (ĐK: $x\ge -\dfrac{1}{2}$ )

$\Leftrightarrow \left( {{x}^{2}}-8x+16 \right)+\left[ \left( 2x+1 \right)-6\sqrt{2x+1}+9 \right]=0$

$\Leftrightarrow {{\left( x-4 \right)}^{2}}+{{\left( \sqrt{2x+1}-3 \right)}^{2}}=0$

$\Leftrightarrow\begin{cases}x-4=0\\\sqrt{2x+1}-3=0\end{cases}$

$\Leftrightarrow\begin{cases}x=4\\2x+1=9\end{cases}$

$\Leftrightarrow\begin{cases}x=4\\x=4\end{cases}$

$\Leftrightarrow x=4$ (nhận)
