\(\Rightarrow x^2-x-5x+5=0\)

\(\Rightarrow\left(x^2-x\right)-\left(5x-5\right)=0\)

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

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

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