\(\sqrt{x^2-2m}+2.\sqrt{x^2-1}=x\ge0\)

Ta có: \(\sqrt{x^2-2m}+2.\sqrt{x^2-1}=x< =>\text{​​}\text{​​}\text{​​}2.\sqrt{x^2-1}=x-\sqrt{x^2-2m}\)

=>\(4.\left(x^2-1\right)=\left(x-\sqrt{x^2-2m}\right)^2\)và \(x-\sqrt{x^2-2m}\ge0< =>x\ge\sqrt{x^2-2m}< =>m\ge0\)

<=>\(4x^2-4=x^2-2x.\sqrt{x^2-2m}+x^2-2m\)

<=>\(2x^2+2m-4=-2x.\sqrt{x^2-2m}\)

<=>\(x^2+m-2=-x.\sqrt{x^2-2m}\)

=>\(\left(x^2+m-2\right)^2=\left(-x\sqrt{x^2-2m}\right)^2\)và \(x^2+m-2\ge0\)

<=>\(x^4+2.\left(m-2\right)x^2+\left(m-2\right)^2=x^4-2m.x^2\)

<=>\(\left(4m-4\right)x^2=-\left(m-2\right)^2\)

-xét m=1=>pt<=>0.x^2=-1(vô lí, loại)

-xét m khác 1

=>\(x^2=\frac{-\left(m-2\right)^2}{4m-4}\)

+Với m>1=>\(x^2=\frac{-\left(m-2\right)^2}{4m-4}< 0\)(vô lí, loại)

+Với 0<_m<1=>\(x^2=\frac{-\left(m-2\right)^2}{4m-4}>0< =>\orbr{\begin{cases}x=-\sqrt{\frac{-\left(m-2\right)^2}{4m-4}}\\x=\sqrt{\frac{-\left(m-2\right)^2}{4m-4}}\end{cases}}\)

Theo điều kiện xác định=>x^2>_1,2m và x^2>_2-m

=>\(\hept{\begin{cases}\frac{-\left(m-2\right)^2}{4m-4}\ge1\\\frac{-\left(m-2\right)^2}{4m-4}\ge2m\end{cases}and\frac{-\left(m-2\right)^2}{4m-4}\ge2-m}< =>\hept{\begin{cases}\frac{\left(m-2\right)^2}{4-4m}\ge1\\\frac{\left(m-2\right)^2}{4-4m}\ge2m\end{cases}and\frac{\left(m-2\right)^2}{4-4m}\ge2-m}\)Vì 4-4m>0=>\(\hept{\begin{cases}\left(m-2\right)^2\ge4-4m\\\left(m-2\right)^2\ge2m\left(4-4m\right)\end{cases}and\left(m-2\right)^2\ge\left(4-4m\right)\left(2-m\right)< =>\hept{\begin{cases}m^2\ge0\\\left(3m-2\right)^2\ge0\end{cases}}}\)và 2/3<_m<_2

Do đó để pt có nghiệm thì 2/3<_m<1
