Substitute yp and its derivatives into the ODE. Equate coefficients of like terms and solve for the constants in yp. Apply initial condition to the general solution (y = yh + yp) to determine the constants in yh. The undetermined coefficients method is usually cumbersome and seldom used in practice.

The method of undetermined coefficients: only applied while p(x) and q(x) are constant, i.e., . Example: . Modification Rule: If a term in your choice for happens to be a solution of the homogeneous ODE, multiply your choice of by x (or by if this solution corresponds to a double root of the characteristic equation of the homogeneous ODE).
