Yes, it makes sense to just use Math.min. *This Instructable is designed for those who have no prior coding knowledge and consider themselves beginners. These are needed to complete and run the code. In other words you simply return $-b / 2a$ but you don't check if $b$ is negative, if it isn't then this is actually the smaller of the two roots not the larger. If it is positive, the equation has two real roots. public static String useQuadraticFormula (double a, double b, double c) { double temp = Math.pow (b, 2) - (4 * a * c); if (temp <= 0) return "These numbers do not compute - they produce an illegal result."; double result1 = (-b + Math.sqrt (temp)) / (2 * a); double result2 = (-b - Math.sqrt (temp)) / (2 * a); return String.valueOf (result1) + ", What screws can be used with Aluminum windows? in Java Programs real number and an imaginary number.
