SUMMARY

The forum discussion focuses on solving a system of n equations defined by the relationships between variables \(x_1, x_2, \ldots, x_n\) for \(n \geq 2\). The equations are structured symmetrically, leading to the observation that if all variables are equal, two solutions emerge: \(x_j = 2\) as a double root and \(x_j = -1\) as a single root. While these solutions satisfy the system, there is no definitive proof that they are the only solutions available.

PREREQUISITES
  • Understanding of polynomial equations and roots
  • Familiarity with algebraic manipulation and symmetry in equations
  • Knowledge of the concept of double roots and single roots
  • Basic skills in mathematical problem-solving techniques
NEXT STEPS
  • Explore the implications of symmetry in polynomial equations
  • Research methods for finding roots of higher-degree polynomials
  • Learn about numerical methods for solving systems of equations
  • Investigate the use of graphing techniques to visualize solutions
USEFUL FOR

Mathematicians, students studying algebra, and anyone interested in solving complex polynomial systems will benefit from this discussion.

Solve the system of $$n$$ equations with unknown $$x_1, x_2, ... , x_n$$, for $$n\ge 2$$:

$$2x_1^3 + 4 =x_1^2 (x_2 +3)$$
$$2x_2^3 + 4 =x_2^2 (x_3 +3)$$
$$......$$
$$2x$$n-13$$+ 4 = $$$$x$$n-12$$(x_n +3)$$
$$2x_n^3 + 4 =x_n^2 (x_1 +3)$$

Can you help me?

The symmetry of the equations led me to wonder what would happen if all the variables were equal. In that case, there are two solutions. $x_j=2$ is a double-root, and $x_j=-1$ is a single root. I don't think there is any guarantee that these are the only solutions, but you can see by inspection that they both solve the system.
