Use the annihilator method to determine the form of a particular solution for the given equation. \( y^{\prime \prime}+16 y^{\prime}+65 y=2 e^{-8 x} \cos x+x \) Find a differential operator that will annihilate the nonhomogeneity \( 2 e^{-8 x} \cos x+x \). \( \square \) (Type the lowest-order annihilator that contains the minimum number of terms. Type your answer in factored or expanded form.)
