### Structure of the Problem Requirements

A quadratic equation has the form ax4 + bx3 + cx2 + dx + e = 0. A general quartic equation (also called a biquadratic equation) is a fourth-order polynomial equation of the form.## Source Code

#include <iostream>

#include <cmath>

#include <windows.h>

using namespace std;

int main() {

float a = 0.0 ;

float b = 0.0 ;

float c = 0.0 ;

float x1 = 0.0 ;

float x2 = 0.0 ;

float dtrmnt = 0.0 ;

float real = 0.0 ;

float imgpart = 0.0 ;

system("color 4a");

cout<<"\n\n\t********** Quadratic Equation *************\n\n\n";

cout << "Enter Coefficients A : ";

cin >> a ;

cout << "\n Enter Coefficients B : ";

cin >> b ;

cout << "\n Enter Coefficients C : ";

cin >> c ;

dtrmnt = b*b - 4*a*c;

if (dtrmnt > 0) {

x1 = (-b + sqrt(dtrmnt)) / (2*a);

x2 = (-b - sqrt(dtrmnt)) / (2*a);

cout<<endl<<endl;

cout << "x1 = " << x1 << endl;

cout << "x2 = " << x2 << endl;

}

else if (dtrmnt == 0) {

x1 = (-b + sqrt(dtrmnt)) / (2*a);

cout<<endl<<endl;

cout << "x1 = x2 =" << x1 << endl;

}

else {

real = -b/(2*a);

imgpart =sqrt(-dtrmnt)/(2*a);

cout<<endl<<endl;

cout << "x1 = " << real << "+" << imgpart << "i" << endl;

cout << "x2 = " << real << "-" << imgpart << "i" << endl;

}

return 0;

}
