The equation has one zero, and the system has three solutions ( 1 real and 2 complex solutions).
<h3>
Solution of the polynomial equation</h3>
The solution of the polynomial equation is determined as follows;
3x³ + x = 2x² + 1
3x³ - 2x² + x - 1 = 0
Thus, we can conclude that the equation has one zero (real solution), and the system has three solutions ( 1 real and 2 complex solutions).
