You are looking for a bounded solution that oscillates in time, so set the above constant to be pure imaginary. Show that if A = iw, where w > 0, then T(t) = Coeiut and X(x) = C1e(1+i)= + C»e¯X1+i)¤ for some real number y > 0. What is y? Hint: you will need to calculate Viw/k. Refer to Section 17.2 of the textbook if you have forgotten how to find roots of complex numbers
