In this problem you will use undetermined coefficients to solve the nonhomogeneous equation ″ 2 ′ = 18 − 4 − − ( 4 ) with initial values ( 0 ) = − 3 and ′ ( 0 ) = − 1. A. Write the characteristic equation for the associated homogeneous equation. (Use r for your variable.) B. Write the fundamental solutions for the associated homogeneous equation. 1 = 2 = C. Write the form of the particular solution and its derivatives. (Use A, B, C, etc. for undetermined coefficients. = ′ = ″ = D. Write the general solution. (Use c1 and c2 for 1 and 2 ). = E. Plug in the initial values and solve for 1 and 2 to find the solution to the initial value problem. = Hint: No fractions are required in the solution or answer to this problem.
