Consider the equation Yk+2 – 6yk+1 + 8yk = 2+ 3k2 – 5 - 3k. (4.146) The characteristic equation is p2 – 6r + 8 = (r – 2)(r – 4) = 0, (4.147) %3D which leads to the following solution of the homogeneous equation: H) = c12* + c24*, (4.148) where c and c2 are arbitrary constants. The families of the terms in R are 2 - (1], k? - [1, k, k²], 3k - [3*). (4.149) The combined family is [1, k, k², 3k] and contains no members that occur in the homogeneous solution. Therefore, the particular solution takes the form (P) = A+ Bk + Ck² + D3*, (4.150) %3D where A, B, C, and D are constants to be determined. Substitution of equation (4.150) into (4.146) and simplifying the resulting expression gives (3A – 4B – 2C) + (3B – 8C)k + 3Ck² – D3* = 2+ 3k2 – 5- 3*. (4.151)
