can anyone give msom light on this question, thanks

find the complete solution of the differential equation

d2y/dx2 – 4 dy/dx + 3y = 65 sin 2 x

find the value of the constantasuch thaty= axe^-1is a solution of the differential equation

d2y/dx2 + 3 dy/dx + 2y = 2 e-x

find the solution for which y=1 and dy/dx =3 when x=0
