x² - x - 6 = 0

⇒ x² + 2x - 3x - 6 = 0

⇒ x.(x + 2) - 3.(x + 2) = 0

⇒ (x - 3).(x + 2) = 0

\(\Rightarrow\left[{}\begin{matrix}x+2=0\\x-3=0\end{matrix}\right.\Rightarrow\left[{}\begin{matrix}x=-2\\x=3\end{matrix}\right.\)

xy - 5y + 2x - 10= (xy + 2x) - (5y + 10) = x.(y + 2) - 5.(y + 2)= (y + 2).(x - 5)
