Verify that the vector xₚ, is a particular solution of the given nonhomogeneous linear p system.

dx/dt = x + 4y + 2t - 5
dy/dt = 3x + 2y - 4t - 12; xₚ = ( 2 )ₜ + ( 3 )
(-1 ) ( 1 )

Writing the system in the form x = AX + F for some coefficient matrix A and vector F, one obtains the following.

Substituting the given vector into the system and simplifying the resulting equations, we find that both equations hold true for any value of t. Therefore, the vector is indeed a particular solution of the given nonhomogeneous linear system.

My pleasure, I’ve been growing my expertise in solving system of linear differential equations problems. Let's verify that the vector xp, is a particular solution of the given nonhomogeneous linear system.

dx / dt =x+4y+2t−5;

dy / dt =3x+2y−4t−12;xp =( 2 −1 )

We can verify that xp is a solution by substituting it into the system and checking if the equation is satisfied.

Steps to solve:

1. Substitute xp into the system:

d / dt (2)=−1+4(−1)+2t−5

d / dt (−1)=3(2)+2(−1)−4t−12

2. Simplify the equations:

d / dt(2)=−7+2t−5

d /dt (−1)=6−4t−12

3. Check if the equations are satisfied:

The first equation becomes −7+2t−5= −7 +2t−5, which is always true.

The second equation becomes 6−4t−12= 6 −4t−12, which is also always true. Therefore, we can conclude that xp is a particular solution of the given nonhomogeneous linear system.
