    Unhappy Another factorising question.

    OK one more problem I have

    6(2x+y)^2-26x-13y+6

    There are several ones like these i need to do but I should be able to do those if I can tackle this one. I have no clue where to start with this one.

    It can be re-written as 6 (2x + y)^2 - 13(2x + y) + 6 which has the form 6a^2 - 13 a + 6. So factorise 6a^2 - 13 a + 6, substitute a = 2x + y and simplify.
