Put these steps of solving a linear equation with constant coefficients in order. 1. Choose and fit a trial particular integral to the right-hand side 2. Add the two parts and apply the initial conditions 3. Write and solve the auxiliary equation 4. Write the complementary function from the roots
Answer: B
The auxiliary equation comes first because its roots decide both the complementary function and whether the trial particular integral needs a factor of \( x \). The two parts are then added, and only the complete general solution can absorb the initial conditions, since the constants belong to the complementary function
