(Assume that k, k₁, and k₂ are all positive.) O The auxiliary equation should have a pair of complex roots a ± ßi where a < 0, so that the solution has the form ex (c₁ cos ẞx + c₂ sin x). The differential equation should have the form y" + k²y = 0 where k = 1 so that the period of the solution is 27. O The differential equation should have the form y" + k²y = 0 where k = 2 so that the period of the solution is é. O The auxiliary equation should have a repeated negative root, so that the solution has the form c₁e-kx + c₂xe-kx O The auxiliary equation should have two positive roots, so that the solution has the form c₁ek₁x + c₂ek₂x O The auxiliary equation should have one positive and one negative root, so that the solution has the form c₁ek₁x + c₂e-K₂x.
