Welcome back BRA-T — missed you this week. Here are the general solutions for the given differential equations using D-operator methods. 1.1 (D^2 - 4D + 4)y = e^2x + e^-2x Step 1: Find the complementary function (y_c). The auxiliary equation is obtained by replacing D with m: m^2 - 4m + 4 = 0 This is a perfect square: (m-2)^2 = 0 The roots are m = 2 (repeated root). For repeated roots, the complementary function is of the form $y_c = (C_1 + C_2
