Question

tìm x

(x-3)x(x-4)=0

Answer 1

\(\left(x-3\right)x\left(x-4\right)=0\)

+ \(x-3=0\) hoặc + \(x-4=0\)

+ \(x-3=0\)

\(x=0+3\)

\(x=3\)

+ \(x-4=0\)

\(x=0+4\)

\(x=4\)

Vậy \(x=3\) hoặc \(x=4\)

Answer 2

Giải:

\(\left(x-3\right)x\left(x-4\right)=0\)

\(\Leftrightarrow\left[{}\begin{matrix}x-3=0\\x=0\\x-4=0\end{matrix}\right.\)

\(\Leftrightarrow\left[{}\begin{matrix}x=3\\x=0\\x=4\end{matrix}\right.\)

Vậy ...
