Em dùng kiểu trâu bò tí!
ĐKXĐ: \(x\in\mathbb{R}\)
PT \(\Leftrightarrow\sqrt{x^2-x+3}=1+\sqrt{x^2+x+2}\)
\(\Leftrightarrow x^2-x+3=x^2+x+3+2\sqrt{x^2+x+2}\)
\(\Leftrightarrow-x=\sqrt{x^2+x+2}\Leftrightarrow\left\{{}\begin{matrix}x\le0\\x^2=x^2+x+2\end{matrix}\right.\Leftrightarrow x=-2\)
Is that true?
