Answer:
[tex]6(2a+b)[/tex]
Step-by-step explanation:
The given expression is
[tex]12a+6b[/tex]
To find the equivalent expression of the given one, we just have to factor.
In this case, the only thing we can do to rewrite is to extract the common greatest factor, which is 6
[tex]12a+6b\\6(2a+b)[/tex]
Therefore, the equivalent expression is
[tex]6(2a+b)[/tex]
