Plz solve all the parts!
1. Solve the following Differential Equations (a) (4D4 - 8D3 – 7D2 + 11D + 6)y = 0. Ans: y=ce-* + c2e2x + cze+ ce- (b) (D3 +6D2 + 12D+8)y = 0, y(0) = 0, 7(0) = 0, y"(0) = 2. Ans y = re-2x (C) y" + 6y" + 11y' + 6y = 0, y(0) = 0, y(0)=1, y"0) =-1. Ans y = 2e-1 - 3e-2x + e-3 (d) y" – 4y" + 14y" - 204 + 25y = 0. Ans y = e((c + c22) cos(2x) + (C3 + C4.c) sin(2x))
