\(\frac{x^2}{\sqrt{3x-2}}-\sqrt{3x-2}\)

tìm x ạ helpp meee

Answer 1

[ʚDʉү_²ƙ⁶ɞ‏]

Theo mình đề bài là: \(\frac{x^2}{\sqrt{3x-2}}=\sqrt{3x-2}\)    (ĐKXĐ: \(x>\frac{3}{2}\))

\(\Leftrightarrow x^2=3x-2\)

\(\Leftrightarrow x^2-3x+2=0\)

\(\Leftrightarrow x-x-2x+2=0\)

\(\Leftrightarrow\left(x-1\right)\left(x-2\right)=0\)

\(\Rightarrow\orbr{\begin{cases}x=1\\x=2\end{cases}}\)

Vậy ....
