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...
In order to solve a cubic equation we use the rational roots theorem to find a set of possible roots for the function, test them to find a real root, construct a factor and then use long division of polynomials or synthetic division to find the other factors. How do you find the roots...
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...

Find a cubi c equation witha+β, β+γ and y+ a as its roots. Express the equation in the form of x3 + ax2 + br+ c=0, where a, band c are constants .已知 a、B和y是方程 2x^3+0x^2+2x+0=3 的三个根,求以 α+β 、β+y和 r+α 和为根的三次方程,并把方程以x^3+...
We’ve already solved this bit. So to find the remaining solutions to our equation, we’re going to make the other part of this product equal to zero. 𝑥 squared minus 𝑥 plus one equals zero. We could solve this in a number of ways. We could use the quadratic formula. Let’s ...
