can you please help me solve this

2. For the following differential equations, determine a suitable form for the particular solution yp(t) if the method of undetermined coefficients is to be used. Except if you are a glutton for punishment, do NOT attempt to figure out the value of the constants. There is no credit for figuring out the value of the constants; however, if you do figure them out and get them wrong, then you loose points. (n) (10 points) Ay" + Ay' ty 2 + De-1/2 + 2 cost.
