Question

(8x-16)(x-5)=0

Answer 1

\(\Rightarrow\left[{}\begin{matrix}8x-16=0\\x-5=0\end{matrix}\right.\Rightarrow\left[{}\begin{matrix}x=2\\x=5\end{matrix}\right.\)

Answer 2

(8x - 16)(x - 5) = 0

<=> 8(x - 2)(x - 5) = 0

<=> \(\left[{}\begin{matrix}x-2=0\\x-5=0\end{matrix}\right.\Leftrightarrow\left[{}\begin{matrix}x=2\\x=5\end{matrix}\right.\)
