Question 50

Multiple Choice

Solve the differential equation using the method of undetermined coefficients.
ytt+5yt+6y=2x2y ^ { tt } + 5 y ^ { t } + 6 y = 2 x ^ { 2 }


A)
y(x) =c1e2x+c2e3x+9108c3y ( x ) = c _ { 1 } e ^ { - 2 x } + c _ { 2 } e ^ { - 3 x } + \frac { 9 } { 108 } c _ { 3 }
B) y(x) =c1e2x+c2e3x+16x2y ( x ) = c _ { 1 } e ^ { - 2 x } + c _ { 2 } e ^ { - 3 x } + \frac { 1 } { 6 } x ^ { 2 }
C) y(x) =c1e2x+c2e3xy ( x ) = c _ { 1 } e ^ { - 2 x } + c _ { 2 } e ^ { - 3 x }
D) y(x) =16x2518x+19108y ( x ) = \frac { 1 } { 6 } x ^ { 2 } - \frac { 5 } { 18 } x + \frac { 19 } { 108 }
E) y(x) =c1e2x+c2e3x+13x259x+1954y ( x ) = c _ { 1 } e ^ { - 2 x } + c _ { 2 } e ^ { - 3 x } + \frac { 1 } { 3 } x ^ { 2 } - \frac { 5 } { 9 } x + \frac { 19 } { 54 }
