Finding the Equilibrium Constant

A mixture of 1 mol of H2O (g) and 1 mol CO (g) is placed in an evacuated 1 liter reaction vessel at 1200 K at equilibrium 0.478 mols of O2 was present. Find Kc

CO(g) + H2O (g)<--------> CO2 (g) + H2(g)

Is this correct?
E = 1-x 1-x <----> 0.478 + x + x

0.478 + x (x) / 1.0-2x+x2
0.478x + x2 It looks like the x2 cancel so we will not do a quadratic and collect like terms to come up with Kc.

My question is, where do I go from here? Do I use a quadratic?
