Create a java program to solve quadratic eqations
Solving a quadratic equation The program must have two methods quadraticEquationRoot1 which takes as input 3 doubles, representing a,b,c and returns the larger of the two roots and quadraticEquationRoot 2 which takes as input 3 doubles, representing a,b, and c (in that order) and returns the smaller of the two roots.

We assume that the numbers a,b,c are chosen so that the square root is never the square root of a negative number

I have the following written down so far. I am not sure on how to introduce the second method

public static void main(string args[]){

}

public static double quadraticEquationRoot1(int a, int b, int c) (){

}

if(Math.sqrt(Math.pow(b, 2) - 4*a*c) == 0)

{

return -b/(2*a);

}else

{

int root1, root2;

root1 = (-b + Math.sqrt(Math.pow(b, 2) - 4*a*c)) / (2*a);

root2 = (-b - Math.sqrt(Math.pow(b, 2) - 4*a*c)) / (2*a);

return Math.max(root1, root2);
}

}
