Determine the equilibrium constant for this reaction

I tried to do the question below and I want to make sure if I did correctly.

The question is:

Ions B and C react to form complex BC. If 15.0 mL of 1.00 M B is combined with 15.0 mL of 1.00 M C, 0.00450 mol of complex BC is formed. Determine the equilibrium constant for this reaction.

Firstly, I converted the total volume 15.0 mL + 15.0 mL = 30 mL to L and I got 0.03L

Secondly, I used the given 0.00450 mol and divided it by 0.03 L and I got 0.15 M for BC

Thirdly, I did the ICE chart

After that, I used the quadratic formula to solve for x and calculate the concentration for each substance, as well as getting the Kc at equilibrium

I got 1.53 for Kc but I am not sure if the whole process is correctly done. Please point out my mistakes, thank you very much.
