Question

5x^2 - 10x - x + 2 = 0

Answer 1

\(\Leftrightarrow5x\left(x-2\right)-\left(x-2\right)=0\\ \Leftrightarrow\left(5x-1\right)\left(x-2\right)=0\\ \Leftrightarrow\left[{}\begin{matrix}x=\dfrac{1}{5}\\x=2\end{matrix}\right.\)

Answer 2

\(5x^2-10x-x+2=0\)

\(\Leftrightarrow\left(x-2\right)\left(5x-1\right)=0\)

\(\Leftrightarrow\left[{}\begin{matrix}x=2\\x=\dfrac{1}{5}\end{matrix}\right.\)
