\displaystyle [br]\begin{equation*}x^2 + 2x - 8x - 16\end{equation*}
\displaystyle [br]\begin{equation*}x^2 + 2x - (8x + 16) \end{equation*}
\displaystyle [br]\begin{equation*}x(x+2) - (8(x+2)) = x(x+2) - 8(x+2) = \cdots \end{equation*}
\displaystyle [br]\begin{equation*}\log 5 + y + \log 2 + 2z\end{equation*}
\displaystyle [br]\begin{equation*}\log 5 + \log 2 + y + 2z\end{equation*}
\displaystyle[br]\begin{equation*}\log (5\times 2) + y + 2z = \log 10 + y + 2z\end{equation*}
\displaystyle [br]\begin{equation*}1 + y + 2z\end{equation*}
