WebSep 7, 2024 · For yp to be a solution to the differential equation, we must find values for A and B such that y″ + 4y′ + 3y = 3x 0 + 4(A) + 3(Ax + B) = 3x 3Ax + (4A + 3B) = 3x. Setting coefficients of like terms equal, we have 3A = 3 4A + 3B = 0. Then, A = 1 and B = − 4 3, so yp(x) = x − 4 3 and the general solution is y(x) = c1e − x + c2e − 3x + x − 4 3.
