Let a, BERbe solutions of the equation z2 + az + b 0 (a, b E R). Given the differential equation y" + ay'+ by = 0. it's true that, (A) if a = B. p(t) = keat (k E R) is its general integral (B) if a = B. p(t) = teat is one of its solutions (C) for all a E R. it has solutions unbounded in (-oo, 0) O (D) if a 3, it has constant, non zero solutions (E) for all a E R it has solutions unbounded in (0, +∞)

i need only ans. i don't need any explanation. thank u
Let a, BERbe solutions of the equation z2 + az + b= 0 (a, b E R). Given the differential equation
y" + ay' + by = 0. it's true that,
(A) if a = B.p(t) = keat (k E R) is its general integral
(B) if a = B. p(t) = teat is one of its solutions
(C) for all a E R. it has solutions unbounded in (-oo, 0)
O (D) if a 3, it has constant, non zero solutions
O (E) for all a ER it has solutions unbounded in (0, +oo)
