# Factorsing! watch

1. 2cx^2 +c (6a+b)x+3abc

I know its pretty basic but I am having issues factorising this and its getting on my nerves!!

The closest I get is:

2cx(x+3a) + b(x+3a)

I know it can be further simplified because that isnt the final answer and I am just not confident on the final steps - any help will be really appreciated.

The first thing you can do is to take out a factor of c from everything. What is left is

which you can factor into linear factors in x.

That's great! Both these terms have a common factor of , if it helps, why don't you write , then you have:

Isn't there a problem in OP's first step? Or have I misread it?

Ah, yes. I assumed that the OP's first step was correct since it looked like the kind of method the question wanted. Having abc at the end makes it rather complicated for what I suspect the OP's level is at, perhaps a typo in the question?

I don't think so; it comes out nice...
