Transcribed Image Text:Solve the given differential equation by undetermined coefficients.
y(x) =
y" +2y'=2x +9-e-2x
exp(2x) (C₁ sin(x) + C² cos(x) ) + x²/4 + x exp(-2x)/4
C₁ exp(-2x) + C₂ x exp(-2x) + x³/3 + x² exp(-2x)/2 + x
C₁ exp(2x) + C₂ exp(-2x) + x/2 + x exp(-2x) + x²
C₁ exp(-2x) + C₂ + x²/2 + x exp(-2x)/2 + 4x
C₁ sin(2x) + C₂ cos(2x) + x²/2 + x exp(-2x)/2 + x³
C₁ exp(x) + C₂ exp(-x) + x/6 + 2x exp(-x)
