Need help with this differential equations please

[Sunex]

Obtain the general solution of the differential equations by using the method of undetermined coefficients (1) y''' - 2y'' + 3y' - 5y = 5sin2x + 10x^2 - 3x - 7 (2) y''' + y' - 5y = 4sinx + 2x^2

Start with breaking up the DEs into Homogeneous and particular equations:
