Unformatted text preview: et . (5 points). 1. The characteristic equation is 0 = r 2 + 2 r3 = ( r + 3)( r1). Thus the general solution is y = C 1 e3 t + C 2 e t . 2. This would correspond to a characteristic equation of 0 = ( r5)( r + 1) = r 24 r5, so a corresponding diﬀerential equation would be y 004 y5 y = 0....
