solve d^3y/dx^3-3d^2y/dx^2+2dy/dx=exp(2x)
Answered by Steve
y"' - 3y" + 2y' = e^(2x)
D(D-1)(D-2)(y) = e^2x

y = (1/4)(c1)e^x + (1/4)(c2)e^(2x) + (1/2)xe^(2x) + c3

solve d^3y/dx^3+4d^2y/dx^2+4dy/dx=exp(-2x)
Answered by Steve
that is just like the previous one. Just review your text section on linear DE's. There must be examples just like your problem.
Answered by assma
how can find on the particular solution of the linear DE's
d^3y/dx^3+4d^2y/dx^2+4dy/dx=exp(-2x)
