Write the auxiliary equation needed to annihilate the given equation in terms of the differential operator D. Write the equation in it's fully factored form:

 y+81y=3x+e2x\displaystyle {y}{''}+{81}{y}={3}{x}+{e}^{{{2}{x}}} 

 

Write the general solution to the differential equation in the form y=yc+yp\displaystyle {y}={y}_{{c}}+{y}_{{p}} in terms of the co-efficients c1,c2,\displaystyle {c}_{{1}},{c}_{{2}},\ldots  (Do not solve for yp\displaystyle {y}_{{p}} !!). Write your solutions in the standard order (polynomials, exponential, cos(x), sin(x)).
