\(\dfrac{x}{-2}=\dfrac{-50}{x}\)
\(x^2=100\)
\(\Rightarrow\left[{}\begin{matrix}x=10\\x=-10\end{matrix}\right.\)
\(\dfrac{x}{-2}=\dfrac{-50}{x}=>x^2=-50\) x -2
=> x2 = 100
=> x = 10 hoặc -10
\(\dfrac{x}{-2}=\dfrac{-50}{x}\)
\(x^2=\left(-50\right).\left(-2\right)\)
\(x^2=100\)
\(x=\left[{}\begin{matrix}10\\-10\end{matrix}\right.\)
\(\dfrac{x}{-2}=\dfrac{-50}{x}\)
Ta có :\(\dfrac{-x}{2}=\dfrac{-x}{50}\)
\(\Rightarrow\dfrac{-x}{50}=\dfrac{-x}{50}\)
\(\Rightarrow x=-1\)
Vậy x=-1
