Factor the x out of the first 2 terms and factor out a 2 from the last 2. Now, notice that you can factor out the blue
At first glance this looked really easy to me. Boy was I proven wrong!
Anyway, I have to factorize:
There's a relationship between the x's and a's since the sum of the coefficients of the first 3 parts is . If this can be turned into a -6 then it would be easier to factorize.
Any help will be greatly appreciated.
