Well, it's only Pure Core 1 Mathematics. I am trying to factorise: 2x^3 - 6x^2 + 2 = 0 Now, you can't use a calculator. I've tried finding a factor using the remainder theorem, but I just can't find a simple one (|x<5|). I am sure they don't expect us to use a complicated number, like a non-integar. So I just need someone to help me with factorising this. Thank you, Stephen.
