The expression to factor is given as:


-5x-15

We can factor this in 2 ways by:

• Taking a 5 as common from both terms

,

• Taking a -5 as common from both terms

First, let's take "5" common from both terms:


\begin{gathered} -5x-15 \\ =5(-x-3) \end{gathered}

Next, let's take "-5" common from both terms:


\begin{gathered} -5x-15 \\ =-5(x+3) \end{gathered}The two ways to factor are:
\begin{gathered} 5(-x-3) \\ \text{and} \\ -5(x+3) \end{gathered}
