Eq. (2.3) is a cubic equation in terms of volume. For this reason, the Van der Waals EOS (and its modifications) is called a cubic EOS. The terms aV2 and b in Eq. (2.1) are the attractive and repulsive terms, respectively. The constants a and b in Eq. (2.1) have physical mean...
Instead, factoring or graphing are used to find the roots of cubic functions. How do you solve a cubic equation without a quadratic? There are two ways to solve a cubic equation without using a quadratic formula: factoring and graphing. These are the steps to use to find the roots of a...
