Answer:

#6ab(2a+5b)#

Here's how I did it:

Explanation:

To factor something, you have to see what everything has in common.

So first we find the LCM (largest common multiple) of #12# and #30#. That is #6#.

We also find the LCM of #a^2b# and #ab^2#, which is #ab#. Now we take out the two LCMs, #6# and #ab#, multiply them by each other, and leave whatever was not factored out added in a parenthesis, like this:
#6ab(2a+5b)#

Hope this helps!
