4. Find a Cauchy-Euler differential equation aa?y" + bæy + cy = 0, where a, b, and c are real constants, if it is known that: (а) т1 = 3 and m2 = -1 are roots of its auxiliary equation; (b) mị = i is a complex root of its auxiliary equation.

What is the least order of a homogenous differential equation with constant coefficients for which y = i 7.6x² + x³e-8x is a solution?

public class TracingExercise public static void main(String[] args) { } int a = 5; int b = 10; int result = firstMethod(a, b); System.out.println("Final Output: " + result); public static int firstMethod (int x, int y) { int z secondMethod(x + y, y); } return zy; public static int secondMethod (int p, int q) { int rp } q; return thirdMethod (r, q); public static int thirdMethod (int s, int t) { return s + t; } 1. What is the output of the method firstMethod when called with the parameters 5 and 10? 2. What value does secondMethod return when called with the results of firstMethod? 3. What is the result of thirdMethod given the outputs from secondMethod? 4. What is the final output printed by the main method?
