### What do we do when we are faced with a cubic equation?

I know that sometimes we need to use the quadratic formula to solve for concentrations, but, what do we do when we are faced with a cubic equation? How do we solve for that?

if I remember correctly, when he discussed ice tables he also mentioned that he wouldn't give us a scenario involving cubic equations. if it came down to it, you would need to remember that if the K value is less than 5%, you can get rid of the x In addition or subtraction to make it a quadratic. I hope that helped.

We won't be given a cubic equation for a chemical equilibrium problem. The 5 percent rule should apply and you can ignore the x values for reactants.
