thanks for the reply. im working through this question. I am not to sure I am doing it right though. K^2+6K+9 = 0 therefore K= -3 and y= A*exp(-3x) + Bx*exp(-3x) y'=-3A*exp(-3x) - 3Bx*exp(-3x) + B*exp(-3x) y(p)= Ax*exp(-3x) y'(p)= A*exp(-3x) - 3Ax*exp(-3x) am i on the...

Im having trouble with this question. can anyone explain please? Homework Statement y'' + 6y' + 9y = x*exp(-3x)3x Homework Equations Find the general solution.
