Đk:\(x\in\left[1;\frac{5}{2}\right]\)
Ta thấy 2 vế luôn dương, bình phương lên đc:
\(\sqrt{\left(5-2x\right)^2}=\sqrt{\left(x-1\right)^2}\)
\(\Leftrightarrow5-2x=x-1\)
\(\Leftrightarrow3x=6\)
\(\Leftrightarrow x=2\)
Đk:\(\frac{5}{2}\le x\le1\)
2 vế dương bình lên ta có:
\(\sqrt{\left(5-2x\right)^2}=\sqrt{\left(x-1\right)^2}\)
\(\Leftrightarrow5-2x=x-1\)
\(\Leftrightarrow3x=6\)
\(\Leftrightarrow x=2\)
