y'' + 3y' + 2y = 24exp(-2x)

2. Relevant equations

y'' + 3y' + 2y = 24exp(-2x)

3. The attempt at a solution

I've solved the characteristic equation and am after the particular solution.

I've let y_p = Aexp(-2x), y_p' = -2Axexp(-2x) and y_p'' = 4Axexp(-2x)

When substituting these terms into the original D.E., I end up with A = 0.

What have I done wrong?
