#=>2x(4x+b)#

Explanation:

You look for common values and variables.

Both terms have #2x# as a common factor. Lets see what this looks like:

#=>2x(4x+b)#

There are no more common factors. However, if you were pushed you could factor out the 4 but in doing so you would need to incorporate a correction in the form of #1/4#. Let me show you what I mean:

#=>2x xx4(x+b/4)# However, I can not see any benefit in doing this!
