Quadratic Equation
Posted by James on October 25, 2001 at 10:20 PM
I have an assignment where i have to enter methods into a quadratic class. the folowing methods must be used: getCoefficient(), computeDiscriminant() (b^2-4ac), displayTwoRealRoots(), displayOneRoot() (if discriminant=0 theres only one solution. it will compute and display that root with formula x= -b/2a I have to add those methods inside main() below. // YOUR NAME HERE // Program 7 // Due October 26, 2001 // This program prompts the user for the coefficients a, b, and c in // the equation a x^2 + b x + c = 0, and then it figures out the roots // using the quadratic equation // // x = (-b +/- sqrt(b^2 - 4ac)) / 2a import jpb.*; public class Quadratic { public static void main(String[] args) { double a, b, c; double discriminant; // Get the coefficients from the user System.out.println("This program solves the quadratic equation: " + "a x^2 + b x + c = 0"); System.out.println("Enter the coefficients"); a = getCoefficient(); b = getCoefficient(); c = getCoefficient(); discriminant = computeDiscriminant(a, b, c); if (discriminant > 0) displayTwoRealRoots (a, b, discriminant); else if (discriminant == 0) displayOneRoot(a, b); else System.out.println("No real roots"); } // methods go here. } I know this is huge, any help is appreciated.
