Can someone please explain how to solve this question, using the quadratic formula?

A reaction mixture is prepared by mixing 0.100 mol SO2, 0.200 mol NO2, 0.100 mol NO, and 0.150 mol SO3 in
a 5.00-L reaction vessel. The reaction SO2(g) NO2(g) ∆ NO(g) SO3(g) is allowed to reach equilibrium at 460 C, when Kc 85.0. What is the equilibrium concentration of each substance?

Calculate Q first to see which direction the reaction would go in. Then do an icebox calculation and set your equilibrium concentrations equal to k. Solve for x and plug those values back into the equilibrium concentrations.
