question 5

Multiple Choice

If $X _ { 1 }$ and $X _ { 2 }$ are solutions of the second order system $\mathbf { X } ^ { \prime } = A \mathbf { X }$ and $\mathrm { X } _ { p }$ is a particular solution of $\mathrm { X } ^ { \prime } = A \mathrm { X } + f ( t )$ , then the general solution of $\mathrm { X } ^ { \prime } = A \mathrm { X } + f ( t )$ is

• A) \(\mathrm { X } _ { 1 } + \mathrm { X } _ { 2 } + \mathrm { X } _ { p }\)
• B) \(\mathbf { X } _ { 1 } + \mathbf { X } _ { 2 } + c _ { 3 } \mathbf { X } _ { p }\)
• C) \(c _ { 1 } \mathbf { X } _ { 1 } + c _ { 2 } \mathbf { X } _ { 2 }\)
• D) \(c _ { 1 } \mathbf { X } _ { 1 } + c _ { 2 } \mathbf { X } _ { 2 } + c _ { 3 } \mathbf { X } _ { p }\)
• E) \(c _ { 1 } \mathbf { X } _ { 1 } + c _ { 2 } \mathbf { X } _ { 2 } + \mathbf { X } _ { p }\)
