Question

5x ( x -1 ) - 3(x-1) = 0

Answer 1

5x(x-1)-3(x-1)=0

(x-1)(5x-3)=0

\(\left[{}\begin{matrix}x-1=0\\5x-3=0\end{matrix}\right.\)\(\Rightarrow\)\(\left[{}\begin{matrix}x-1=0\\5x=3\end{matrix}\right.\)\(\Rightarrow\)\(\left[{}\begin{matrix}x=1\\x=\dfrac{3}{5}\end{matrix}\right.\)

vậy x = 1

x = \(\dfrac{3}{5}\)

Answer 2

\(5x\left(x-1\right)-3\left(x-1\right)=0\)

\(\Rightarrow\left(5x-3\right)\left(x-1\right)=0\)

\(\Rightarrow\left[{}\begin{matrix}5x-3=0\\x-1=0\end{matrix}\right.\)

\(\Rightarrow\left[{}\begin{matrix}x=\dfrac{3}{5}\\x=1\end{matrix}\right.\)
