When can you assume the change is insignificant when solving cubic equations?

As Lavelle said in today's lecture, a change is insignificant when the K constant is less than 1 * 10^-3 or 0.001. I would assume the same thing will apply if the K constant is greater than 10^3 or 1,000.

When K is less than 10^-3. You can also check at the end of the calculation to see if the change is less than 5% to see if the approximation works out.
