[1SN]Given \(a_ 0\ldots a_{n}βˆˆβ„‚\) constants, with \(a_ nβ‰  0\), and defining \(p(x)=a_ n x^{n} + a_{n-1} x^{n-1} + \dots a_{1} x + a_ 0\), describe all possible solutions \(f\) of

\[ p(D) f = 0~ . \]

Show that the solution space is a vector space (based on the field \(β„‚\) of complex numbers) of dimension \(n\).

( Hint. Factorize the polynomial and take advantage of previous exercises. ).
