The equilibrium constant, K, for the following reaction is 3.78×10-2 at 530 K.

PCl5(g) PCl3(g) + Cl2(g)

An equilibrium mixture of the three gases in a 5.47 L container at 530 K contains 0.295 M PCl5, 0.106 M PCl3 and 0.106 M Cl2.

What will be the concentrations of the three gases once equilibrium has been reestablished, if the volume of the container is increased to 12.1 L?

[PCl5] = M

[PCl3] = M

[Cl2] = M

please help me!

I don't understand how you rearrange to get an expression of the form ax2+bx+c=0 and use the quadratic formula to solve for x. I have been struggle on this part. please help me to understand.
