Answer:

-2 (2x +14)

-4 (x + 7)

Step-by-step explanation:

We are given the expression:


-4x-28

We will factor it as shown below:

I.


\begin{gathered} -4x-28 \\ \text{Both terms have a common factor of ''2''. Hence, we can divide and factor by 2. We have:} \\ 2(-2x-14) \\ \text{Re-writing the expression, we have:} \\ -2(2x+14) \\ \\ \therefore-2(2x+14) \end{gathered}

II.


\begin{gathered} -4x-28 \\ \text{Both terms have a greatest common factor of ''-4''. Hence, we can divide and factor by ''-4''. We have:} \\ 4(-x-7) \\ \text{Re-writing the expression, we have:} \\ -4(x+7) \\ \\ \therefore-4(x+7) \end{gathered}
