Question

The "REVERSIBLE" chemical reaction-
A + B <--> C + D
Kc = CD / AB =4.4

Concentration at the start and after equilibrium-
A = 1.00 M --> (1.00 - X) M
B = 2.00 M --> (2.00 - X) M
C = 0.00 M --> X M
D = 0.00 M --> X M
4.4 = X^2 / (1.00-X)(2.00 - X)

I'm not sure what to do next, Can someone please help me out?

You solve for x. I think you use the FOIL method

The chemistry is right. It's an algebra problem now. Solve for X. Chopsticks is right. Expand the denominator by using FOIL, gather terms and solve the quadratic equation.
