    You need to put it into the form ax^2 + bx + c = 0

    then you can put a b and c into the equation.

    Have a go first, we will help you further if you are still stuck.

    subtract 2x from both sides so you get: (^2=squared)

    3x^2-2x+1=0

    the work the problem from there...

    2 +- sqr. root of -2^2-4*1*3
    2*2
