Question 851490
In order to factor this expression, you need to factor out the common terms.  You can factor out 6b, since 6 is divisible by all of the terms in the expression, and b, because b is present in each of the terms.  So, once you factor 6b out, you will have:


6b(12ab - 7c + 4a).  This is the furthest you can factor, so this is your fully factored expression.
