Multiple Choice

Solve the differential equation ytt+2yt=4ex by the method of undetermined y ^ { tt } + 2 y ^ { t } = 4 e ^ { x } \text { by the method of undetermined } coefficients.


A) y=C1+C2e3x+43exy = C _ { 1 } + C _ { 2 } e ^ { 3 x } + \frac { 4 } { 3 } e ^ { x }
B) y=C1+C2e3x43exy = C _ { 1 } + C _ { 2 } e ^ { - 3 x } - \frac { 4 } { 3 } e ^ { x }
C) y=C1+C2e2x+43exy = C _ { 1 } + C _ { 2 } e ^ { - 2 x } + \frac { 4 } { 3 } e ^ { x }
D) y=C1+C2e3x3exy = C _ { 1 } + C _ { 2 } e ^ { 3 x } - 3 e ^ { x }
E) y=C1+C2e2x+4exy = C _ { 1 } + C _ { 2 } e ^ { - 2 x } + 4 e ^ { x }
