Question

Factor out the greatest common factor from - 12a - 8a

Answer 1

The given expression is

`-12a-8a^2`

The greatest common factor is

`-4a`

Now, we factor out the greatest common factor and we get the expression inside the parenthesis by division

`\begin{gathered} -(12a)/(-4a)=3 \\ -(8a^2)/(-4a)=2a \end{gathered}`

Hence, the final expression is C.

`-4a(3+2a)`
