Read 3 floating-point numbers. After, print the roots of bhaskara’s formula. If it's impossible to calculate the roots because a division by zero or a square root of a negative number, presents the message “Impossivel calcular”.

Input

Read 3 floating-point numbers A, B and C.

Output

Print the result with 5 digits after the decimal point or the message if it is impossible to calculate.

//Problem



public class URI_1036 {



 public static void main(String[] args) {

  float A, B, C, R1, R2;

  Scanner input =new Scanner(System.in);

  A = input.nextFloat();

  B = input.nextFloat();

  C = input.nextFloat();

  

  if ((A == 0) || (((B*B) -(4*A*C)) < 0)) {

   System.out.print("Impossivel calcular\n");

  }else {

   R1 =(float) ((-B + Math.sqrt(((B*B) -(4*A*C)))) / (2*A));

   R2 =(float) ((-B - Math.sqrt(((B*B) -(4*A*C)))) / (2*A));

   

   System.out.printf("R1 = %.5f\n", R1);

   System.out.printf("R2 = %.5f\n", R2);

  }

 }
