calculating x cubically

how do we solve for x when it comes out to a cubic function?

I don't think we will have to know how to do that for this class. Here's the link that Dr. Lavelle sent out in an email on solving cubics: viewtopic.php?f=49&t=40016

I think the outline just referred to the assumption that we can make when K<10^-3 that x is negligible. Without this assumption, it would usually create a cubic equation.
