A third order linear, homogeneous DE whose general solution is y(t) = C₁e-t + C₂e + C3e²t is: [Hint: The general solution implies that r=-1,1 and 2 are the roots of the characteristi equation. Hence r+1, r-1 and r-2 are the factors of the characteristic equation.] O A.y"" - 2y"+y' + 2y = 0 O B. y" + 2y"+y' + 2y = 0 Ocy" - 2y" - y' + 2y = 0 O D. none of these OE.y"" + 2y" - y' + 2y = 0
