Ta có \(\sqrt{x^2-2x+5}+\sqrt{x^2+2x+10}=\sqrt{29}\)
<=> \(\sqrt{x^2-2x+5}=\sqrt{29}-\sqrt{x^2+2x+10}\)
<=> \(x^2-2x+5=x^2+2x+39-2\sqrt{29\left(x^2+2x+10\right)}\)
<=> \(2\sqrt{29x^2+58x+290}=4x+34\)
<=> \(\sqrt{29x^2+58x+290}=2x+17\)
<=> \(29x^2+58x+290=4x^2+68x+289\)
<=> \(25x^2-10x+1=0\)
<=> \(\left(5x-1\right)^2=0\)
<=> \(x=\frac{1}{5}\)
