How to calculate the roots of polynomial equations in Go?

In Go, you can calculate the roots of polynomial equations using the "github.com/npcomplete/polynomial" package.

Here's an example code that demonstrates how to calculate the roots of a polynomial equation:

package main

import (
	"fmt"
	"math/rand"

	"github.com/npcomplete/polynomial"
)

func main() {
	// Create a random polynomial of degree 3
	coefficients := []float64{
		rand.Float64(), rand.Float64(), rand.Float64(), rand.Float64(),
	}
	p, err := polynomial.New(coefficients)
	if err != nil {
		fmt.Printf("Error creating polynomial: %v\n", err)
		return
	}

	// Calculate the roots of the polynomial
	roots := p.Roots()

	// Print the roots
	fmt.Println("Roots of the polynomial:")
	for _, root := range roots {
		fmt.Println(root)
	}
}

In this example, we first create a random polynomial of degree 3 using the coefficients generated by the rand.Float64() method. Then, we use the Roots() method provided by the polynomial package to calculate the roots of the polynomial.

Finally, we iterate over the roots and print them to the console.
