Question

Write a program in java to input co-efficients of quadratic equation ax^2+bx+c=0 where a is not equal to 0 and find the roots if possible ​

Answer 1

Answer:

public class QuadraticEquationSolver

{

public static void main(String[] args)

{

/*Suppose our Quadratic Equation to be solved

* is 2x2 + 6x + 4 = 0 .

* (Assuming that both roots are real valued)

*

* General form of a Quadratic Equation is

* ax2 + bx + c = 0 where 'a' is not equal to 0

*

* Hence a = 2, b = 6 and c = 4.

*/

int a = 2;

int b = 6;

int c = 4;

//Finding out the roots

double temp1 = Math.sqrt(b * b - 4 * a * c);

double root1 = (-b + temp1) / (2*a) ;

double root2 = (-b - temp1) / (2*a) ;

System.out.println("The roots of the Quadratic Equation \"2x2 + 6x + 4 = 0\" are "+root1+" and "+root2);

}

}
