3.) Given that y, () = (t + 2)- e' and y,t) = e - 2 are both solutions of a certain second order homogeneous linear differential equation: y" + Ay' + By = 0 Answer each question below. For each true/false question, state a brief reason that justifies your answer. a.) Show that these two solutions are linearly independent. b.) True or False: y, and y, form a fundamental set of solutions of this equation.

10. Find the solution of the differential equation (D° + 8D° + 16D)y = 0 A. Y = C, + (C2 + C3x)cos y = C+ (C2 + C3x)cos А. 3x + (C, + C3x)sin 3x y = C + (C2 + C3x²)cos C. 2x + (C, + C3x)sin 2x y = C, + (C2 + C3x?)cos В. 2x + (C, + C3x²)sin 2x D. 3x + (C, + C3x²)sin 3x
