    Expand the left hand side and re-arrange the equation into the form

    quartic = 0.

    The quartic factorises as (x - 1)(2x + 11)(2x^2 + 9x+24).

    The details are left for you to do. Please show your full working and where you get stuck if you need more help.

    and in process i get common terms that i assume as a that will become as (a+2)( a+3)

    This makes no sense. Go back and read what I suggested that you do.
